Hi Beccs! Re Orange Walk, its not a big tourist area. There is Cuello, and it is on the property of the rum distillery of the same name. They will let you in. Not much left of it. There is another one in the area, Nohmul as I recall, and I think north of Orange Walk, also on private property, but most people are willing to let you in. Ask around, there's a house mear a water tower, as I recall, where the owner lives. They are very nice, you won't have a problem, will even take you to it. There was a place there called, inovatively enough, the Diner to eat at. Only went there once, but it seemed OK. Don't know a thing about Santa Cruz, probably been through it but don't recall. You don't mean Santa Rita, do you?
What will you be teaching? It sounds like a great endeavor. Have fun! Its a small country, so you can do much in the area. Don't forget the baboon sanctuary.
