Hi...
The FM's are working visas for NOT mexican citizen and RFC....that's a registration in Hacienda ( IRS ). When you work here as an independent photographer you have to pay taxes on you income like anywhere else , that's why many hotel will ask you for that from your outside vendors....
good luck and I hope that helped a bit.

The whole yucatan peninsula looks like a swiss cheese, there are Cenotes everywhere. From every hotel at the riviera maya you can find an opening into the cave system ( which are the fresh water springs or cenotes ) close by. Each of them are one of a kind, sometimes you have to walk down a ladder, get into a cavern or you have like a little lake. The water is crystel clear with a lot of vegetation around and beautiful rock formation at the entrance.
My favorite is Grand Cenote in Tulum. Is one of natures best build.
I have been diving most of the caves in the riviera maya .... for any questions regarding cenotes don't hesitate to contact me. I will be more then pleased to help you out.
