NOT sure where to head off next?

We've rounded up the TUI hotels with some of the best swimming pools in the world.

Known as one of the top travel companies in the UK, TUI has some of the world's best hotels at its fingertips.

These hotels usually include cutting-edge technology, modern interior design, a variety of amenities and activities - and some amazing swimming pools.

MGM Grand Hotel, Las Vegas

Home to four supersized swimming pools, a lazy river and a handful of hot tubs - there's a bit of something for everyone at this Las Vegas hotel.

The MGM Grand Hotel is also famous for the Wet Republic Pool parties, which take place in a dedicated party pool.

Kitted out with daybeds, cabanas, bars and headlined by big-name DJs like Steve Aoki and Zedd, it's safe to say the hotel has earned its distinction.

Pool parties are held every Thursday to Monday between March and November, starting at 11am and wrapping up around 7pm.

TUI BLUE Atlantic Aeneas Resort, Cyprus

TUI has created and owns the hotel brand TUI Blue, with more than 100 hotels in 20 countries across the world.

One of those is the TUI BLUE Atlantica Aeneas Resort, which pulls out all the stops when it comes to family fun.

There are six swimming pools at the hotel, including one with its very own swim-up bar and another pool that's perfect for toddlers with a pirate-themed, slide-filled splash zone.

The main pool at the hotel is geared up for underwater photography too - even for those holidaymakers who don't have an underwater camera.

This is because the pool has specially-designed port holes where guests can take underwater photos.

Unlike other hotels, the swim-up rooms at the TUI BLUE Atlantica Aeneas Resort are connected to the main pool by a winding river.

Hard Rock Riviera Maya Heaven, Mexico

The swimming pool at the Hard Rock Riviera Maya Heaven is lined with sunloungers.

The pool snakes its way beneath bridges and around palm tree-topped islands, which means guests can get from one side of the hotel to the other without getting out of the water.

And that's not all, the hotel has its own private cove-style beach with white sand and overwater Bali beds.

JW Marriott Khao Lak Resort, Thailand

Holidaymakers at the JW Marriott Khao Lak Resort will be able to swim in the longest pool in south-east Asia.

The huge pool is formed of a network of lagoons and canals that weave their way around the hotel in the pool.

Other features include swim-up bars and tiny islands dotted with palm trees.

And those guests who stay in a swim-up suite will even be able to have their breakfast delivered to them in a canoe.

Gran Melia Palacio De Isora, Tenerife

The swimming pool at this hotel stretches for a whopping 260 metres and has more than 70 water sunbeds.

There are also whirlpools and jets dotted throughout the saltwater pool too.

The pool also unravels all the way down to the beach, where it merges into an infinity pool - meaning holidaymakers can swim with a sea-view backdrop.
