Treasure Island used to be known as sort of a playful place with its pirate show and yo-ho-ho attitude. Recently it is more about exotic tropical islands with sexy women :) There is Mystere - the Cirque du Soleil show, and the tropical themed rooms. The price is mid-range for the strip and the hotel is in the perfect spot to explore everywhere.
