Zip Line Excursion

[Cruiser052]

February 2007 will be our 2nd time to Belize on a RC cruise and thought about doing the zip line excursion. From what I have been reading, Nacho and Cynthia seems to be the way to go? Is it a better excursion than what is offered by the cruise lines or is it just less expensive? Can a group of 2 go with Nacho and Cynthia or do they compile a list and when they feel they have enough to make it worth while they schedule you? And, is it safe to book an excursion not associated with the cruise line? Just curious and a bit skeptical. Any info would be helpful.

I, too, am interested in doing the zip-line only, not the cave tubing, as my DH can't take chilly water due to a health condition. I'm wondering if anyone has done JUST the zip-line, who they went with, and if it is possible to book this at the tender pier, that very day. Any advice would be appreciated.
