PADI Cancun

[freedivernd]

I don't think the dive shop I was thinking about will work out from where you're staying.  I know "scuba cancun" is in the hotel zone on Kukulcán from doing an internet seach and I would bet there are other dive shops that will be right close by.  I know when you're staying at an all inclusive it's tough to spend day trips away from all the free food and drinks and that's what it would entail to get yourself to some of the dive shops down south.
best of luck to you.. and don't forget when you get back into this area, that our diving is just as good as mexico's except this time of year and even then, some would argue that. .. yeah, right....
