Oasis Palm Beach resort, Cancun

[bikinichick]

I'll be staying at Oasis Palm Beach this December. I hear from the tour operator that there's a dive shop at the resort but I haven't been able to get the name of the dive operator so that I can look them up. Has anyone stayed at Oasis Palm Beach? I'd appreciate your thoughts on the dive shop there, and their name.

Also I'd welcome any recommendations on Cancun generally, which operators were good or bad, and why.

Thanks in advance,
Katy
