DET:I don't have a good answer for your location. You are about 25 kilometers south of PDC and 15 Kilometers north of Akumal. Both locations have dive shops. I don't know about locations in between. The resort may have something on site, which may cost a little more. Maybe Puerto Aventuras has a shop. It's about 6 kilometers north of you. Good luck!
There is two very good Padi dive shops(The Akumal dive Center & The Akumal Dive Shop) in Akumal and some very good reefs that would be very appropriate for new divers.
I have 4 daughters who dive and I can recommend The Akumal Dive Center as a good solution for you.
Best of Luck,
Dave
