This was my first experience with tubing. The hotel's site says , and I quote, 'our special river tube rafts ... with protective bottoms...guides go with you and ensure your safety.'
My daughter and I were the only tubers at 1:30, February 3rd so we each had our own guide. The protective bottom is a piece of canvas (unpadded). My tube hit a submerged rock three times and the last time really hurt! I came out with a bruised tailbone which will take weeks or months to heal; I can barely lift myself off a seat.
My guide said that that morning, about 7 people had flipped off their tube and into the river.
I caution all readers against this activity.
