How did you like diving in the Cenote? My husband just got certified and our dives this trip to Tulum will be his first since his certification. Our plan is to do a dive or two in Akumal one or two days, but if the Cenote dive was cool, we'd do that. He's worried that he'll feel claustrophobic and trapped. Did you feel that at all or are the really big under there? Thanks for your tips and trip report!
