Yankedog... go back and read the original first post of the thread. The poster DID mean crocodiles and NOT sandles.
Glad you had a good time. But there are other cave tour operators that offer extended tours over the cruise ship booked tours also. Reggie Tours (they also have a website) and Xtreme Cave Tubing Tours comes to mind. I am sure there are others. This is the first time I have heard of Yhoney, how did you find them?
