Toopure4u- There is a beach for kids to swim, it's protected from the surf by rocks and a good sunning beach, there a restaurant/bar on the beach and other diversions like scuba diving. You should definately call and make your reservation prior to going, this excursion is very popular and sells out. The web address is listed above and it's a toll free call to set up your swim. All of the interactions with the dolphins, pulls, pushes etc. involves 2 dolphins and you. These animals will have no problems moving you in the water at all. It doesn't matter what you weigh!...Mark
