I won't be there (it is hot enough in Sacramento; Quintana Roo will be too.) But if you want to eat some dinky di, er, genuine, Yucatecan food, get yourself to Los Almendros for some good regional cooking. It's part of a chain, one that started in a small town in Yucatán and has a couple of restaurants in Mérida as well, but it's a very good introduction to the unique regional cooking of the peninsula. The hotel should be able to look it up for you - not too far from the bullring, iirc.

They have an illustrated menu, with descriptive information - so you know what you are getting when you order the sopa de lima (chicken and lime broth,) poc chuc (marinated BBQ style pork) fish tikin xic (garlic and achiote, or annatto in English,) panuchos, pollo or cochinita pibil (slow-roasted chicken or pork pibil style, some sweet and some spice,) etc.
