We are all in our mid 50's (4 of us) did a zip line adventure in the Caribbean booked throught the cruise line and had a wonderful The precautions with the company were impressive. They had 2 lines going across in case one broke. The safety hardness also had 2 sets of security belts. I was pleasantly surprised about the equipment. Security was foremost in the guides minds. Another reason for booking with the cruise lines since they inspect and take responsibilty.
