If the ancient lost city of Atlantis existed, it must have had sophisticated yet ancient designs for its power generation, diving machines and other structures. The Atlantis resort designers have gone to great lengths to imagine what this city would have looked like and have created its life and eventual watery doom while integrating them with the modern features of a luxury hotel.Decorations reflect real and mythical creatures - seahorses, flying horses, helmeted domes, giant bronze doors with writing and designs, an entire fantasy world. As a theme resort, it compares favorably with the best of Las Vegas. The hotel has the largest open air aquarium in the world and certainly the largest aquarium of any kind in the Caribbean. The aquarium specializes in native tropical species and the tanks include the ruins and sculptures of Atlantis. One tank gives the visual impression of the new Atlantis towers rising from the old.
