Hi! You're going to have a wonderful time. There is plenty to eat there, but I would avoid the vendors. If you are looking for economical places, try Ambergris Delights and Mickeys, they are owned by the people who work there, and will listen to you. Also, I am quite fond of the little palapa at my hotel, the Paradise Resort Hotel, just north of the cemetary. Only opened for breakfast and lunch, but they will work with you. Jambel Jerk will work with you, too. Lots of other great places, just call first, and ask around. These are the most cooperative folks. Trust me, they'll work with you. Problem with the vendors is you may have a bit of a language problem, and not get your needs across to them. Have a great time.
