A sister property to Dolphin Cove, Dolphins Plus offers some of the same programs and the age requirement is lower. The cheapest option, a Natural Swim program, begins with a one-hour briefing; then you enter the water to become totally immersed in the dolphins' world. In this visual orientation, participants snorkel but are not allowed to touch the dolphins. For tactile interaction (kissing, fin tows, etc.), sign up for the Structured Swim program, which is more expensive.
