Thanks for the informative and frank advice. I am leaning towards just snorkeling with a guide. I am very comfortable in the water and snorkeling, but think I would have a hard time getting in and out of the kayak. (My partner on the other hand would be fine) No worries about me trying to surf the reef! Too dangerous for me. I won't even snorkel close to the surf at Mexico Rocks/Tres Cocos. We'll see how how I feel about doing this once we get to San Pedro. 25 days and counting!! laugh Thanks again. mobunny
