Just wanted to tell you our experience on the rapid river----my husband and another guy both got forced down one of the rapid areas at the same time and my husband's tube bounced into one of the cement boulders which scraped his head and ripped off his toenail. His tube then flipped over and since it was in one of the rapid areas with lots of water being pushed into the area, it took him a long time to get back on his tube. I was ready to exit the water at this stage, but my kids were having fun and my husband said we might as well keep going. However, I didn't feel comfortable letting my 8 year old daughter continue without a life vest (she is a very strong swimmer) so we stopped and got one for her. Later on, in another rapid area we saw a little girl get bounced off of her double tube. I will say a lifeguard got her out of the water quickly, but her father had no way to react and his tube was instantly whisked further down the river. I'm sure he was in a total panic and I'm not sure how he met up with his daughter again. If you are not a strong swimmer, definitely wear a lifevest-- they do have them in both child and adult sizes.
