We were surprised 65 people could space out out this boat, but we did. Boat is beautiful. Music -beach, summer, fun dance--playing the entire time. Captain and crew very kind. You spend about an hour looking at the dolphins. They swim under and around the boat as they please-- saw some baby dophins. Captain will turn in slow circles so everyone has a view. Park on shell island for an hour. The last hour you go back and there is dancing! Honestly not much to see when u snorkel, especially if you have done this in places with reefs before. However, the water is clear and warmish...sand white. The snorkel equipment tasted clean. There's a short slide off the back of the boat. Orrrrr most will exit to she'll island by going down steps and get belly/chest deep into water(I'm 5'2")... They will give u a snorkel/mask and if u want a lifejacket to float with, one of those as well. There weren't really any shells immediately near us but it was late in the day (2:00 tour, so 3 pm on shell island). Small boat bathrooms so wear your bathing suit under clothes. Bar has cans of beer, soda, Gatorade... Some rice crispy treats, Lance's cheese and crackers and slim Jim's. Waves were calm, but took some non drowsy Dramamine anyway...overall a nice 3 hour boat ride, forthe price.
