hey, angela, when are you and dave going?
We went to to eastern Caribbean last summer with my 5 year old and she loved the Kon Tiki boat excursion in St Thomas. The crew was great and entertaining. On the way to the beach they give the history of st Thomas while opening the glass bottom boat....then we stopped at the beach for approx 90 minutes (i think...maybe a little longer)...there was a group of locals who sold BBQ food and snacks on the beach...made to order....their hamburgers were the best! and then we went back to the boat where the crew played the steel drums and played the limbo as well as the Macarena....it was a lot of fun!
Oh! The St Martaan 12 metre race is the kids favorite on the Eastern. It isn't listed right now as an excursion(?), but it is a hands down favorite. Racing America's Cup sailboats. Fun for everyone!
