That's funny - we were also in Cabo last September (diving too of course)We dove in La Paz. It was fantastic!
Anyway, I don't know what to tell you about the Blue Hole, but I'm sure others will know. I did see that one dive is a 130 foot shelf dive. My husband has only been certified for two years and he's going to do it. Hopefully we'll also get some other diving in - maybe the outer atolls or some closer in reef dives. we're open to anything!
