Northern Girl -you must be so excited. The tequila bar sounds cool, we are thinking about a cigar roller.
I have a list of excursions and things on our wedding website. finleychierchie.com
But this site is also a good idea. Riviera Maya Tours, Activities and Excursions
Xel-Ha and Tulum was a WHOLE day experience, it was really cool, but I think X-Carat is closer. Lots of fun things out there, and Playa Del Carmen (town) is great too, for shopping and the whole experience.
