The Dig is a series of aquariums located beneath the lobby of the Royal Towers and is the world’s largest open air marine habitat. Hundreds of different aquatic species can be spotted in the Dig’s various tanks such as angelfish, sharks, manta rays, and various types of jellyfish. The goal of The Dig is to provide guests with a taste of life in the legendary destroyed city of Atlantis. If one observes the bottom of the floors in the different aquariums, wreckage and debris will be scattered about representing the “Lost City of Atlantis.”

A Predator Lagoon is full of sawsharks, barracudas and stingrays. A 100-foot (30 m) clear acrylic tunnel runs underwater, allowing visitors unobstructed views of the marine environment.
