This will be my third time to Cozumel so I promised my DH that we could do the Mayan ruins this time instead of beach/shopping &/or Carlos & Charlie's!
Our group has been discussing doing the cave tubing & or jungle canopy tour (zip line) in Belize but I just read a post that a passenger has drowed in the cave tubing trip this week because the waters are too high and currents too rough - bet those excursions will be cancelled. I usually don't book my excursions until I get on the ship anyway...
I have heard that the snorkeling in Honduras is excellent so we might do that. Read the member reviews on cruise critic dot com - people always add comments about the excursions there.
I'm sure you'll have a blast! You're just nervous because you don't know what to expect. Our family was nervous the first time too but now we are cruise addicts! See you in 22 days!!
