We booked a combo excursion from the cruise ship that included tubing the White River, a short lunch and cruise, and then a hike up Dunns River Falls. It was excellent and took the whole day. They got us back to the ship just prior to sailing but we were told ahead of time it was an all day excursion. The inter tubing was great for the first half; that is where the light rapids are. There is a guide and his dogs, but the guide was there to keep everyone safe and keep people together. The dog was not a problem at all, as written in another review. Everyone is required to wear a life jacket, but it was NOT cumbersome or a problem at all. My five year old was nervous prior to getting in the water, but within seconds he was laughing and having a ball. The other reviewers are correct in that they stop you half way to buy pictures for $6 each. The pictures are ONLY $6 for a reason. It is best to take a waterproof camera. I put my Droid in a waterproof pouch and it took excellent video and pictures. The second half of the river is more of a lazy river float trip, but still relaxing. As I said, we were too have a boat ride to Dunn's River, so our float trip went past some minor industrial boat docks on the way to the beach. I think most floaters end prior to that area though. Overall, this is a great family adventure. I will write a seperate review of the falls portion.
