The Dolphin Boat. Youngsters—and the young at heart—will love a cruise on the Dolphin Boat, which allows you to swim with the cute and friendly animals. The dolphins and tour guides have developed a close relationship over the years, so you're guaranteed to get up close. In fact, if you don't get into the water to swim with the dolphins, they will refund the difference between the watch and the swim.
