I have to ask what is your #1 most favorite spot in PDC area?
Being from the midwest US and without much else to go on, our dive class instructors said if all else is the same to go with a 5 star padi dive center when you have the choice. This definately helps cut down on the choices. I see Tank-Ha does Cozumel dives direct from PDC, where the other ones have you take a ferry over and use some other dive center once you get to Cozumel. Or so it appears to me. Any experience here?
