I have dove Hawaii, and Costa Rica, now going on a cruise I will have to book my excursions on my own, will go through a PADI shop, will need to rent equipment. Where best to dive? We will be in ports of Cozumel, Belize City, and Roatan and Costa Maya, am thinking its between Belize City and Roatan. I would love to see dolphins, whale sharks, or mantas or sting rays, I was a divemaster, haven't dove since 2006 so its been awhile, 70+ feet diving doesnt bother me, heard the currents can be strong in certain areas, that can be bothersome...Any suggestions on where to dive and with whom to book? Thank you
