Well, I'd love to do the Cancuncare one but we'll miss the date. Is there anything else offered in Cancun that's similar? We'll be heading to Cancun next week. Preferably no kids and a little on the wild side...
To my knowledge there aren't any other adult themed / no kids cruises. But the regular tours are still fun. There are details on my page linked below: http://www.cancuncare.com/Isla_Mujeres/tour.htm
