Two visiting cousins from overseas and I (a resident) chose this tour as it seemed to have all the features we were hoping for: working up to the "big" lines, tropical scenery, safety, and something that we "over 50s" could handle. This choice with Andrew and Rob as our guides did not disappoint. They were funny, charming, well-informed, and attentive to our comfort. There was also a family with younger members in our group and thanks to Andrew and Rob, all of us were confident with the lines. It's an activity that is well worth the cost and we would do it again in a heartbeat!
