Is bigger always better? Not necessarily – but some hotels have turned sheer scale into a spectacle. From Singapore and Macao (pictured) to Las Vegas and beyond, these sprawling resorts rank among the world’s largest by room count. Many come with all the bells and whistles: vast casinos, record-breaking pools, indoor theme parks and more.

Looming over Atlantic City’s Marina District, the golden-glass Borgata Hotel Casino & Spa has been a landmark since 2003. One of three mega-resorts in Renaissance Pointe, it has around 2,000 rooms, 14 restaurants, two nightclubs, five pools and a vast casino.

In 2025, it added 25,000 square feet (2,323sqm) of new gaming space, a high-limit lounge, private salons and a Pan-Asian restaurant, further cementing its status as one of the city’s most stylish stays.

Despite having around 2,700 rooms following a suite conversion in 2019, the Parisian Macao is by no means the largest hotel in Macao, China’s answer to Las Vegas – but it’s certainly among the most distinctive.

Opened in 2016 at the southern end of the Cotai Strip, this integrated resort includes a 1,200-seat theatre, water park and hundreds of shops, all styled after the City of Light. A replica of the Eiffel Tower – complete with nightly sound and light shows – anchors the Parisian theme.

The first of Sin City’s mega-resorts on our list, Harrah’s Las Vegas opened in 1973 as the Holiday Casino and was rebranded in 1992. Now operated by Caesars Entertainment, the resort completed a $200 million renovation of its 2,542 rooms and suites by 2021.

Among them are some of the city’s most spacious stays, including the Penthouse Suite, which spans over 2,000 square feet (186sqm) and features a full-sized bar, gaming table and knock-out views, of course.

Since opening in 2010, this expansive luxury hotel on Singapore’s Marina Bay has been one of the largest in the world, with 2,561 rooms and suites spread across its three 55-storey towers. The pièce de résistance is the SkyPark, which appears to float across the towers.

Alongside its three rooftop restaurants sits the world’s largest rooftop infinity pool, measuring 492 feet (150m) in length. A major expansion is set to begin in 2025, including a fourth tower with around 570 suites, its own SkyPark, a 15,000-seat arena, additional restaurants and pools.

From its cruise ships to its theme parks, Disney doesn’t do things by halves – and the Pop Century Resort at Walt Disney World is no exception. One of the brand’s largest hotels, it has nearly 2,900 rooms spread across motel-style buildings, each themed around a different decade from the 1950s to the 1990s.

Expect giant jukeboxes, yo-yos and Play-Doh tubs dotted about the grounds, all centred around a colourful pool complex. Open since 2003, the resort is currently undergoing a phased room refresh due to run through summer 2026.

Perched along the oceanfront of Waikiki Beach, this vast hotel started life as the low-rise Niumalu Hotel in 1928. Today, it sprawls across 22 acres – with 2,860 rooms, 18 restaurants and bars, more than 80 shops and five pools – including the 5,000-square-foot (1,524sqm) Paradise Pool, which features the longest slide in Waikiki.

A phased renovation of the Rainbow Tower is currently underway and due to complete in early 2026, while a newly approved 36-storey tower is set to begin construction in 2026, adding over 500 more rooms to this ever-growing resort.

There’s a definite sense of joie de vivre about this well-known Las Vegas landmark, which opened in 1999, bringing a little Parisian charm to the Strip. Spanning 24 acres, the resort features 3,672 guestrooms – including 756 newly renovated rooms in the recently added Versailles Tower – an 85,000-square-foot (7,896sqm) casino and striking replicas of French landmarks.

These include a 50-storey Eiffel Tower, façades of the Louvre and the Paris Opera House, the Arc de Triomphe and a 34-storey hotel tower inspired by the Hôtel de Ville. Take the lift to the top of the tower for one of the best views in Sin City.

Between them, Park MGM and NoMad Las Vegas offer a total of 2,993 rooms and suites. Described as 'two distinct luxury hotel experiences under one roof', the pair opened in 2019 following a £418 million ($550m) transformation of the former Monte Carlo Hotel.

Park MGM is home to the Las Vegas outpost of the Italian food hall Eataly and became the first smoke-free casino on the Strip. NoMad occupies the top floors as a more intimate, boutique-style stay – though its branding is expected to change in 2026 following the sale of the NoMad name.

It might have toned down its pirate theme, but this swashbuckling resort still has epic proportions. Treasure Island opened in a central location on the Las Vegas Strip in 1993 and features 2,885 rooms and suites.

It originally drew crowds with its pirates and pyrotechnics, though its signature Sirens of TI show was retired in 2013. Tropical island vibes still remain, however. Now privately owned by Phil Ruffin, the hotel joined Radisson’s portfolio in 2019 and has since undergone room renovations and ongoing upgrades.

With 3,000 suites, The Venetian is the second-largest hotel in Macao by room count. A sister property to the Las Vegas original, this opulent all-suite resort sits on the Cotai Strip, an entertainment hub built on reclaimed land.

It features a 376,000-square-foot (114,605sqm) gaming area and the 15,000-seat Cotai Arena, which underwent a $150 million renovation in late 2024, adding VIP suites, enhanced acoustics and backstage upgrades. Its replica Venice – complete with canals, gondola rides and St Mark's Square – is unmissable.

One of the new breed of large but understated contemporary hotels in traditionally over-the-top Sin City, the Cosmopolitan of Las Vegas has around 3,000 rooms to its name.

With a cool, contemporary feel, there are no gimmicks or themes here, just ultra-luxe suites and high-end restaurants, swanky lounge bars and standout clubs (its poolside Marquee Dayclub is one of the city’s hottest tickets).

Inspired by the legend of the lost city of Atlantis, this larger-than-life resort on Paradise Island opened in 1998 and is now the largest in the Caribbean, with 3,805 rooms and suites across multiple towers.

A £762 million ($1bn) expansion in 2007 added The Cove and The Reef, while a £118 million ($150m) transformation completed in 2025 updated The Royal’s guest rooms, casino and public spaces, and introduced new dining venues, escape rooms, mini-golf and a beach reserve. The resort also features a marina, a theatre and Aquaventure – a 41-acre water park.

Sin City newcomer Resorts World Las Vegas has 3,506 guest rooms across three distinct hotels: Las Vegas Hilton, Conrad Las Vegas and Crockfords Las Vegas. Opened in June 2021 at the north end of the Strip, it was the first integrated resort built there in over a decade.

The property features a 117,000-square-foot (35,662sqm) casino, over 50 food and drink venues and a 5,000-capacity theatre. Its 5.5-acre pool complex, with nine pools and panoramic views, is the largest elevated pool deck in Las Vegas. The 88-acre site also has space reserved for future expansion.

Kitsch and fabulous, the iconic Flamingo is the Strip’s oldest operating resort. Opened in 1946 with just 105 rooms under mobster Bugsy Siegel, it has grown into a 3,460-room property with 225 suites and 16 villas.

Today, it features a mix of dining, entertainment, a wildlife habitat and a 15-acre Caribbean-style water playground. In spring 2025, it unveiled a £15.8 million ($20m) revamp of its GO Pool complex, adding five pools, a swim-up bar, VIP cabanas and rain-curtain waterfalls.

The individual rooms might be on the small side but Shinagawa Prince Hotel is the largest hotel in Japan (and one of the largest in the world), with over 3,500 rooms and suites across its three towers.

Built in 1992 near Shinagawa station, the super-sized complex has indoor and outdoor pools, numerous restaurants, an aquarium, cinema, a bowling centre and no less than 24 karaoke rooms. 

Is it a circus, a casino or a hotel? Try all three. The historic Circus Circus opened in 1968 and has remained a firm family favourite ever since. The cavernous resort has 3,767 rooms and suites and is home to the world’s largest permanent circus, as well as the five-acre indoor amusement park, Adventuredome.

Bought by billionaire Phil Ruffin from MGM Resorts in 2019 for £629 million ($825m), the property has since undergone around £23 million ($30m) in renovations. Although Ruffin previously announced plans for a new water park and theatre, these have not come to fruition – and the entire 102-acre site is now listed for sale.

In a city full of over-the-top hotels, the Bellagio stands out for its relatively understated Italian sophistication – but that’s not to say it isn’t spectacular. One of the largest hotels in Las Vegas with 3,933 guest rooms and suites, it’s renowned for the Fountains of Bellagio: an eight-and-a-half-acre lake with 1,200 dancing water jets.

An £87 million ($110m) renovation of the hotel's Spa Tower was completed in 2023, and a major expansion project known as Project Mojave – adding new dining, retail and entertainment spaces – is currently under review.

With Roman-inspired extravagance at its core, Caesars Palace opened in 1966 as Las Vegas’ first themed resort, drawing celebrities and high rollers with its lavish casino, restaurants and star-studded events. Today, the mega-resort has 3,960 rooms and suites across six towers.

Among its signature Graeco-Roman features is the 4,300-seat Colosseum, home to many A-list residencies. A major expansion is currently under review, including a new 1,000-room tower, 200,000 square feet (18,580sqm) of convention space and a 50,000-square-foot (4,645sqm) casino extension.

Opening at the southern end of the Strip in 1990, Las Vegas’s kitsch fairytale castle-themed resort still draws in the customers to its 3,981 guest rooms.

With its colourful turrets, drawbridges and the long-running dinner show Tournament of Kings – inspired by the legends of King Arthur and performed in the resort’s 900-seat theatre – it’s especially popular with families looking for a little Las Vegas magic.

Opening in 2009 with a sleek and contemporary look, Aria spans over six million square feet (185,000sqm), with more than 4,000 guest rooms and suites. The curvilinear glass, steel and stone building, designed by architectural firm Pelli Clarke Pelli, is also one of the largest buildings in the world to have achieved LEED Gold status.

Aria’s fine art collection is one of the resort’s USPs – especially striking is the grand lobby's Silver River, an 84-foot (26m) silver cast of the Colorado River by artist Maya Lin.

Epic, theatrical and unmistakably Egyptian, the Luxor has been turning heads since 1993, its black glass pyramid shooting a beam of light into the night sky while guests inside roam among giant sphinxes, pharaohs and soaring palms. With 4,407 rooms and suites across the pyramid and twin towers, it remains one of Vegas’s largest resorts.

Recent additions like a high-tech esports arena and a 15,000-square-foot (1,394sqm) immersive playground keep things fresh – but change is coming. A £7.1 billion ($9bn) redevelopment plan could see Luxor replaced by a futuristic twin-tower mega-resort by 2029.

This sophisticated mega-resort, which opened at the northern end of the Las Vegas Strip in 2005, has 4,750 rooms and suites spread across the Wynn and Encore towers. With its gleaming curved façade and bold branding, subtlety isn’t Wynn’s strong suit – but who cares when you’re surrounded by such decadent delights?

Among its standout features are two gaming floors, the only resort golf course on the Strip and the Lake of Dreams, a nightly multimedia show set around a three-acre lake. 

Glitzy super-resort Mandalay Bay lies at the southernmost tip of the Strip. The complex includes 3,209 rooms in the main tower, plus the all-suite Delano Las Vegas in a connected tower and a Four Seasons Hotel occupying floors 35 to 39.

As well as a vast array of shops, bars, restaurants, concert venues and nightclubs, the resort features an 11-acre tropical water area with more than 2,700 tonnes of real sand. Its Shark Reef Aquarium is home to more than 3,400 animals across 140 species, including over a dozen types of shark.

When it comes to extravagance and scale, Macao’s hotels give Las Vegas a run for its money – none more so than the super-luxe resort The Londoner. Described as a 'bold British-themed reimagining' of what was formerly Sands Cotai Central, it has a total of 4,426 rooms and suites across four hotel towers.

Impressive replicas of the Houses of Parliament, Big Ben and a Crystal Palace-style atrium are among its standout features, along with 106,000 square feet (9,840sqm) of gaming space. A further £800 million ($1bn) renovation of retail, dining and wellness offerings was completed in April 2025.

The MGM Grand lies at the southern end of the super-hotel-lined Strip and is one of the largest hotel resorts in the US, with 5,044 rooms and suites. Its vast 171,500-square-foot (15,930sqm) casino features around 1,500 slot machines and 128 table games. You know you’re in for a grand old time the moment you pass beneath the resort’s iconic 45-foot (14m) bronze lion – the largest of its kind in the country.

A £236 million ($300m) renovation of all 4,212 main tower rooms is underway and set to complete by the end of 2025, adding more premium suites to this Las Vegas giant.

In a city that likes to roll big, this supersized resort is the largest and most extravagant of them all. The Venetian Resort on the Strip consists of three all-suite towers: the Venetian, the Palazzo and the Venezia.

All together it has a staggering 7,093 rooms and suites, making it the second largest hotel in the world. It has over 40 restaurants too and various Venice-themed features, most famously its gondola rides along a replica of Venice’s Grand Canal.

You’ll want to get your bearings quickly at this mammoth hotel in Malaysia. Officially the largest hotel in the world by room count, First World Hotel is part of Resorts World Genting and has a staggering 7,351 guest rooms across its three rainbow-coloured towers.

There’s no extravagance here – this is a functional hotel located in the Genting Highlands, a popular resort area perched on Mount Ulu Kali, about an hour north of Kuala Lumpur. The surrounding area is home to theme parks, casinos, shopping malls and scenic hiking trails.
