I don't know if this has been mentioned before, but in case some of you want to push your Spanish learning up a notch and know the language specific to the Yucatan, there is a Yucatecan Spanish dictionary that has been out for a while. The 5th edition came out in 2013 and can be found on Amazon at http://www.amazon.co...n/dp/0988433753. According to this review, physical copies are (or were) also available in Mérida: http://hamacapress.com/dictionary
I recently bought the Kindle version and it seems pretty exhaustive, at 119 pages. There was a hotel clerk last month who suggested that I start learning some slang, and I could barely understand what he was telling me when he started speaking it on purpose. Hopefully, this dictionary should help.
