Did the White river tubing a couple of years ago and had a blast!!
I would do it again if I had the chance.
the innertubes had a plywood bottom and you got a little paddle to push off the sides with. There was a small "rapid" area, and we had a good waterfight splashing with the paddles. water was clean and refreshing. We were in shade most of the time due to the tree canopy so the temp was comfortable. The water wasnt to deep I think you could probably stand up in it and not be in over your head for most of the river. We had a good time. at the end you got a bottled drink water, soda, or Red Stripe, and a sample of some jerk chicken.
The guides were nice as well and you got a little tour driving up to the river and coming back.
