but you can't pre-book it because of the computer's limitations. you have to ask when you get on board. our son is not quite 3 1/2, and there was another boy on board who was not even 3. they just can't go snorkeling. they do have vests for kids that size to wear. on the way out (we did in the morning, so it's not really better, as someone thought it may be), lots of people were getting sick in the back. my oldest and i sat out from on the webbing (ds loved getting splashed with the waves) while dh was back with youngest and middle ds. on way back to magic, it was much calmer and we all rode up front on the webbing.
this was my personal favorite of our trip....something i will want to do again and again. my only complaint was that there wasn't enough time spent at the island...most of it was spent getting there and back, plus trying to get the anchor to stay in the sand once we "docked."
