Julie, we have done Dunn's twice, once on a cruise and then with relatives when we stayed at an all inclusive. It's an experience and be sure that everyone has water shoes as it can be slippery and does make it alot easier on the feet. As far as the rafting thing, we have done the River Brae in Jamaica. We had our own raft and handler. It took all of an hour or more and we did see beautiful sites and flora and fauna. They try to sell you several times toward the end of the rafting. Their were very little white water on this river. Enjoy !
