We did it and we had a blast, but I did not go thru the cruise line as they went to a smaller zip line place for more money. We got a contact thru the orphanage there for a guy that picked all of us up (17 of us) and charged us $20 per a person to drive us around wherever we wanted to go all day. While the adults did the zip line, again my favorite shore excursion now, even over the stingrays in Grand Cayman, he brought some of the adults with the younger kids to the Iguana Farm. If you look up on line the orphanage there in Roatan you can email them to get the contact info for someone to help you, and also consider bringing something for the orphanage, they depend on us cruisers.
