"Each week-long visit to Poseidon includes two nights underwater and four nights in either of the island villas. The oceanic experience will be further enhanced by the option to maneuver a three-passenger Triton submarine. You will also be able to sip a martini underwater while exploring the ocean’s depths in the resort's luxury submarine.

Above water, you can laze by the resort's pool or take to the skies para-sailing. Other facilities include a nine-hole golf course, tennis courts and a health club. The resort features six restaurants and seven bars, an underwater library and lounge, a theater area and a conference room. There will even be an underwater wedding chapel for those keen to say ‘I do’ in the deep blue."
