The Atlantis Underwater Suite boasts awesome underwater views of the 65,000 marine inhabitants of the lost city of Atlantis. Each of the underwater suites also comes with an ensuite bathroom which grants guests a floor to ceiling view of the underwater Ambassador Lagoon. OK, so it doesn't come cheap (£5,500 a night to be precise!) - but you can still get your glimpse of the incredible array of sealife on a day trip to the hotel's Lost Chambers marine water park for a fraction of the price.
