My husband and two sons, 16 and 17, got certified last year in Maui. They are looking forward to scuba diving in Cozumel. We are staying at Iberostar Paraiso Maya and know we will have to take a taxi to Playa del Carmen and get on the first ferry which leaves at 8. Is there a reputable diving company that will accomodate a little later departure in the morning in order to dive? We've seen afternoon dives leave at 1, but we'd like to leave around 9-9:30 if possible? Any help would be appreciated!
