We did it and had a blast!! It was the best excursion of the trip. You got a short tour of the island while driveing up to the river and back to the ship. The river is comfortably cool, not to deep or fast. There were a couple of mini "rapids" enough to make it exciting but not scary. The inner tubes have a plywood or metal bottom to them so you wont bump your bottom but you will get wet. They give you a liitle wooden oar and there were plenty of guides to help. At the end we got drinks and a taste of Jerk chicken with the option to buy more. They also take pictures on the way to sell at the end. Throughout the cruise we would run into people that were on the excursion and have a laugh. You should have a great time!!
