Whenever I visit Las Vegas, I always stop by the Forum Shops to watch the Fall of Atlantis show and the best part about this showis it's FREE! The show is located in the far end of the Forum Shops with the huge fish tank and video screens around the top part of the walls. It's near Cheesecake Factory and Abercrombie & Fitch and it can get very crowded with tourists and visitors holding their cameras and kids running around waiting for the show to start. They have security around the fountains to prevent anyone from jumping in the water while the show is playing.
The performers are not real people but are electronic statues that move like real people and look somewhat realistic. A lot of fire and water is used for special effects and has a great storyline about jealousy and having control that led to the destruction of this fabled city.
