My adult daughter, my wife and I did the 7 mile tubing trip with about 25 other folks. I had a wonderful time. One just can't fathom floating on innertubes through multiple caverns and what one might see, The guides were very helpful. I never felt uncomfortable or threatened. Our group was the first trip in about 5 days because of high water. We did the whole trip. The cruise ship crowd were not travelling because of issues in the city. The lunch provided was very interesting. If a tourist were hesitant to eat raw fruits and vegetables, especially after being carted in several guide's backpacks, then that tourist might go hungry.
As I said, the guides were very attentive: it may have been my grey hair but there were some younger klutzes, esp the fellow who almost immediately burst his innertube on the bamboo and never did figure out how to maneuver, who probably needed more attention than I did. My wife and daughter felt a little uneasy at times when they became separated from the group by a few hundred feet. The short hikes apparently around more treacherous stretches of the river were quite muddy and required sure footedness-not enjoyed by all our group.
I would surely do this again if I were to return to these parts and recommend it to all but the very least adventuresome.
