First time... where?

Hi,

I'm new to the forums and new to SCUBA. I have done my bookwork, but need to do my OW dives for my PADI certification. I have a week off in October, and free airfare to Cancun. I'm trying to decide between finishing my dives in Cancun, or in Playa del Carmen. Any input will be great. Also, if anyone has experience with any dive shops in either location I would appreciate it!

Thanks,
Amanda

Cozumel is the place to dive in the area, a ferry ride across from PDC.
