What's special about Treasure Island, for families?

Families love the waterpark resort concept: an indoor waterpark is attached right to your resort, and entrance tickets are included in your room rate.

At Treasure Island, the Bay of Dreams indoor waterpark is reached by an enclosed climate-controlled skywalk. During summer months, guests can also play free in a nearby 35-acre outdoor water park, Family Land.

Room rates start as low as $89/night, but can climb to over $300 at peak periods for suites that can sleep up to eight. The section with deluxe suites is called "Captain's Quarters."
