We've all played this game. We love to dream about how we'd spend it. So when it comes to travel, there's no more exciting question than: where would I go if I won the lottery? From private jet safaris to renting your very own island in the Maldives, here are just a few of the extravagant getaways we’d book if we came into a billion or two...

If even the most luxurious hotel rooms in the world aren’t for you, then you need to take advantage of this staggering package: you can have private use of India’s most exclusive royal residences from a very kingly £1,080,000. Ampersand Travel’s King of the Castle package gives guests the chance to live in three of India’s most fabled royal estates: the Lake Palace in Udaipur, Umaid Bhawan Palace in Johpur and Rambagh Palace in Jaipur.

With three nights in each, you’ll experience living in the former set of the James Bond film Octopussy, the sixth largest private residence in the world and the former home to the Maharaja of Jaipur. Just be warned: it will be hard to go back to reality after this.

After your lottery win, you could be forgiven for not wanting to stay in just one country: which is why andBeyond’s Private Jet Expeditions, covering several African countries, look so appealing. With different tours covering different areas, prices start from around £90,000 per person. 

You can choose from a variety of itineraries once you book your private jet experiences, from a southern Africa experience including a tour of South Africa, Zimbabwe, Botswana and Namibia, to an east Africa and Beyond tour, covering Kenya, Tanzania and Rwanda. Plus, once you’re in the more remote bush destinations, expect a combination of private jets, turbo-propelled, fixed-wing aircraft and helicopters. There’s no no-frills with this package.

Forget lacklustre exercise classes or forgotten gym memberships: for a wellbeing retreat that’s on another level, try Aleenta Phuket Resort & Spa’s Mastermind 2.0 Retreat, for a cool £80,000.

The four-week bespoke programme takes a holistic approach to overcoming stress, with intensive therapy, a tailored nutritional plan and an array of rejuvenating spa treatments. There’s even a specialised form of CBT where an in-house psychotherapist works with clients to identify physical, emotional and psychological responses by highlighting behavioural patterns.

Where’s a place that’s endlessly fascinating, vastly unexplored and guaranteed not to be overrun with tourists? Antarctica, of course. With Black Tomato, you can fly from Cape Town to Antarctica by private jet from £70,000 per person.

During the eight-night itinerary, visitors will sleep in pods designed to spot the rarely-seen aurora australis (the southern cousin of the northern lights), visit the lowest point on Earth and take part in rock climbing, abseiling and kite-skiing. For those who don't want a particularly active trip, you can also opt for easy, relaxing excursions: visit one of the local science bases, taking part in gentle treks or simply drink in the majestic scenery.

For lottery winners who are passionate about conservation, there’s no better trip to take than Natural World Safaris’ Journey’s to Nature’s Edge expedition. Costing a cool £777,423, the journey gives guests the chance to come face-to-face with 18 of the most vulnerable species in 12 different countries across the planet.

The expedition spans the globe to seek out the rare creatures in danger of extinction. Potential sightings include northern white rhinos in Kenya, mountain gorillas in Rwanda, wild dogs in Botswana, Bengal tigers and snow leopards in India, penguins in Antarctica, sun bears in Borneo, polar bears in the Arctic and jaguars in Brazil. It's the trip of a lifetime for conservationists with a healthy bank balance.

If you’re fascinated by all things geographical, you cant miss the Four Seasons Hotels & Resorts’ pop-up overnight volcano experience on the Island of Hawaii. The 27-hour overnight experience at Four Seasons Resort Hualalai costs from £32,500 for up to four people. Guests are whisked away by helicopter with a world-leading volcanologist to take in the beauty of the northern Kohala Mountains and see imposing waterfalls, hidden valleys and black sand beaches.

You’ll also take part in a guided bike tour to see the point where the lava flow meets the ocean at Kamokuna, and will even get the chance to do some whale-watching from the comfort of a helicopter. You'll then check in to the luxury Rainforest Cottage Hideaway, set within a 1,000-year-old rainforest, where you’ll enjoy your own personal chef and butler for the evening.

Simple Instagram snaps just aren’t enough to impress anymore, so those looking for a true social media boost should consider a sailing trip in Myanmar that takes in pristine scenery on a private luxury yacht, accompanied, of course, by a drone cameraman who has worked on blockbusters such as James Bond and Star Wars. The experience costs £125,000, but who can put a price on thousands of new followers?

The trip involves sailing through the incredibly beautiful Mergui Archipelago, located in Myanmar’s far southern Tanintharyi Region. Made up of 800 near-deserted islands with dreamy white sands, thick dense jungles and clear waters, it’s a breathtaking journey. Those on board can swim, snorkel, spot wildlife and even spend time with the local inhabitants of the islands, the Mukon people. Plus, let’s not forget that you’ll come home with a truly epic video.

If you’ve got a large portion of the world’s riches all to yourself, you can understand why other guests might be a bit of a pain. Wouldn't it be nice to have the whole place to yourself? That’s why Velaa Private Island – the super-luxurious Maldivian island – can be fully rented out to guests for a cool £777,500 for four nights.

Whether you’re treating colleagues, family or friends to the experience of a lifetime on this exceptional island – or simply enjoying its beauty for yourself – you’re guaranteed privacy, enjoyment and first-class service in gorgeous surroundings.

It’s hard to beat Alaska if you’re looking for luxury in truly wild surroundings. With this itinerary – costing £88,000 per person – you’ll be whisked to the USA’s largest state by private jet to experience just some of what Alaska has to offer.

While you’re there, you’ll enjoy private flights to watch grizzly bears fishing for salmon, kayaking, rafting, hiking, back country skiing, heli-fishing, deep sea fishing and more, all in incomparable surroundings.

As beautiful as Africa is to explore on the ground, it’s perhaps even more spectacular to gaze at from the air. That’s why a cross-continental private flying safari is such a good idea. From the Atlantic Ocean to the Indian Ocean, this 15 day trip takes in Namibia, Botswana, Zambia, Malawi and Mozambique, and costs £120,000 for six people. 

While of course there’s the amazing accommodation and activities you’d expect with this sort of price tag, the aerial view is the cherry on top. It's a colourful ride, with the yellow and orange deserts of Namibia, green in the Okavango Delta in Botswana, brown in the savannah and bush in Zambia, and turquoise in the waters of Lake Malawi and around Mozambique’s coral islands. It’ll be a challenge returning to the grey of the city after this.

Adventure lovers need to book a flight straight to New Zealand and sign up for Hands Up Holiday’s 14-day active adventure. Costing £45,000, be warned: this trip isn’t for the sleepy or indolent, as you’ll be constantly moving to take in everything New Zealand has to offer.

Just a few of the things you’ll be doing include helicopter flights, zip lining, wine tasting, sailing, parasailing, skydiving, zorbing, sky swinging, bungee jumping, cruising, white-water rafting, glacial hiking, heli-mountain biking and canyoning. You’ll also get the chance to visit everywhere from Auckland and the Bay of Islands to Rotorua and Queenstown. Phew.

If your lucky lottery numbers are read out, chances are that you’ll forget all about 5-star luxury and want the next level up: the 7-star experience. The world’s first 7-star hotel, Dubai’s Burj Al Arab Jumeirah, is the first word in over-the-top opulence, so why not go for seven nights in its Royal Suites, costing a total of £105,000?

The enormous Royal Suite not only has a bold colour scheme and sumptuous furnishings, but also has its own private lift, library and cinema room with magnificent views over the Arabian Gulf. Plus, this isn't your ordinary hotel room: you’ll have your own hall and marble and gold staircase, a four-poster rotating canopy bed, two master bathrooms with full-size Jacuzzis, 24-carat gold iPads, a private dining room, dressing rooms and an area to entertain guests in too.

As any good personal trainer will tell you, you can’t just spend a few weeks being healthy and expect everything to change. You have to make wellbeing part of your lifestyle. And if you can afford to spend £156,000 on it, try Health and Fitness Travel’s year-long round-the-world wellness trip.

You’ll travel to 20 different countries, from Australia and Brazil to Thailand and Turkey, stopping at some of the world’s most acclaimed spas on the way. There are all sorts of wellness opportunities awaiting as you hop off your business class flight, from kickboxing sessions in Ibiza to Tai Chi classes on the summit of Vietnam’s Marble Mountains. If you like to put your health first and experience some life-changing adventures, this is the trip of a lifetime.

There’s nothing like a yacht to spell out luxury – and Crystal Yacht Expedition Cruises’ 62-guest Crystal Esprit, a boutique hotel on water, can be chartered for a week from around £326,797. With 31 all-suite, butler-serviced rooms, gorgeous interiors and inviting social spaces, you’d be forgiven for wanting to stay onboard, but there’s plenty to enjoy off the ship too. 

The retractable marina, tucked neatly into the extravagant vessel, contains a lifetime’s worth of water toys, including water skis, wakeboards, ocean kayaks, Skidoo jet skis, two 10-person zodiacs, an in-ocean pool, and fishing and snorkel equipment. There’s even a three-person submarine to take you underwater without getting wet.

If you can’t decide on just one destination and want to travel to several countries in ease, then you need to book one of TCS World Travel’s Four Seasons Trips, where for the princely sum of £120,900 per person, you'll travel the world by private jet, stopping off at some of the world’s best Four Seasons hotels on the way. 

For truly hassle-free travel, every little detail is taken care of on this trip: suitcases are magically delivered to hotel rooms, and guests are even offered a purse of local currency on arrival in each different country, so they can buy whatever they want beyond the meals and tours already set up for them. The 24-day journey travels across four continents, beginning in Hawaii before travelling on to Bora Bora, Sydney, Bali, Thailand, India, Dubai, Prague and London.

There's nothing that says "I've conquered the world" more than climbing Mount Everest to its peak, but the perilous expedition doesn't come cheap: it costs up to £100,000 once you've factored in paying for your flight, the gear, training, the permit to climb the mountain and the cost of Sherpas.

So why spend all that money to put your life in danger, battle freezing temperatures and push your body to its absolute limit? Why climb Mount Everest? As George Mallory famously said, because it's there.

Is there any adventure greater than travelling to space? Thanks to Sir Richard Branson and Virgin Galactic, you don't need to indulge that childhood dream of becoming an astronaut: just book your seat aboard the world’s first commercial space line for a cool $250,000 (approximately £192,678). 

So far, over 500 people have reserved their seats, and Branson himself has said he hopes to have passengers in space by the end of 2018, so don't miss out: you could be one of the first people on board the world-changing space line.

Imagine if your home magically moved every night so that you woke in new, exotic places each morning, from Papua New Guinea to Alaska. Impossible, right? Not if you live on board the only private residential ship at sea, The World, which continually circumnavigates the globe, taking in some of the planet's most spectacular sights. Costing from £1.5 million for a studio apartment, you can also opt for enormous three-bedroom, three-bathroom homes.

You can choose to live on board all year round or spend a few weeks or months on the ship. Solely owned by her residents – currently 142 families from 19 countries around the world – there is a small selection of homes available for resale every year, so if you're interested in seeing the world in the most hassle-free manner imaginable, you'd better start saving up.
