My husband and I were on a 14 day cruise and we selected this excursion. It was wonderful, probably the best part of the entire vacation. Only one downside ... we were bitten by some kind of bug and we itched for days. I would recommend layering your bug spray with several layers. I spayed but it was obviously not enough. However, this would not prevent us for going on this excursion again. FYI: I have a severe fear of heights however, I was able to do this excursion with no problem.
