What could be better than sunbathing on a pool deck perched far above the city? Couple this with some great cocktails and celebrity guests and you have a recipe for fun. Here's the ultimate guide to the world's most luxurious rooftop pools.

Some good news! Despite looking incredibly posh, some of them may actually be within your budget range.
Try these tips for obtaining affordable luxury:

• Book in advance.
• Book during the off-peak periods.
• If you plan on staying longer, try and negotiate for a better nightly rate.

1. Marina Bay Sands, Singapore

This hotel redefines the two words 'rooftop pool'. It's truly awe-inspiring in scale and costed many billions of Singaporean dollars to build. Perched 55 storeys above the heart of Singapore, the Marina Bay Sands has rapidly become an icon in its own right in the glittering Singaporean landscape. The rooftop pool is cantilevered and therefore seems to be floating above the city. It spans the length of three Olympic swimming pools and is arguably the most spectacular infinity pool in the world. The roof top area is a stunning and monumental architectural feat. If you do stay here, you may not want to leave. Indeed if you don't leave for a few weeks, you may bankrupt yourself for the rest of your life.

2. Shoreditch House, London

Shoreditch House takes 'exclusive' to new heights with its elitist members only policy. Although Shoreditch House is strictly speaking a private club, if you can wrangle your way in somehow, then this is the ultimate place to hang out in London during the summer. The building was a shabby old warehouse in East London that's been turned from drab to fab. Nowadays the movers and shakers of the media and fashion industries along with celebrities hang out here. The rooftop pool is accompanied by a lawn area for barefoot romps, a cozy open fire and plenty of lounges. There are also places to bed down when it all gets too much.

3. The Joule, Dallas

This striking cantilevered pool juts out of the 10^th floor of Dallas' down-town district. So you will literally be swimming over the top of morning commuters. As they rush to work, you can enjoy a pre-breakfast swim! There's also a lush poolside service with an interesting cocktail list and plenty of decadent cuisine.

4. The Vine, Madeira, Portugal

Escape the dreary winter in Australia by hopping on a long-haul flight to the sunny Madeira region in Portugal. The Vine is a boutique hotel with luxurious touches everywhere. Like a 20 metre long jacuzzi, a solarium bar and a jaw-dropping infinity pool. Enjoy the dusk descending over the city while sampling some local speciality wines such as the eponymous Madeira wine. On site there's an Alsace-inspired restaurant that's run by culinary genius Antoine Westermann, whose restaurants have earned him three Michelin stars.

Andaz is strictly party central, so if that's your thing then bring your coolest poolside outfits and get ready to go wild. Prince Harry frequents the place along with Kim Kardashian. If star-spotting and name-dropping are more of a turn-on than a turn-off for you – then this is your home away from home.

This fancy hotel lives up to its name – it's shaped like a boat! Everything about this place oozes quirky luxury. Designed by architect Ruy Ohtake, with interiors by João Armentano, there are idiosyncratic and edgy touches that make it an interesting experience to stay. Such as an enormous pool with an underwater sound system that spans the length of the roof. The pool is illuminated a crimson colour at night. Why you ask? Because they can! If you're peckish then check out the multi-ethnic menu at Skye bar and restaurant while vibrant Sao Paolo sighs and hums below.

One of a swathe of luxe hotels in KL, the Pacific Regency have an exceptional rooftop bar that's a cut above the rest. The Luna Bar spans the vast rooftop area and affords sparkling views onto the 88-storey Petronas Twin Towers and other glittering skyscrapers. You can wander in there for drinks and hang out. Although the pool itself is reserved the guests, it's worth paying for the privilege.
