I was looking for information on Costa Maya cabanas on this site before we went to Caye Caulker but cut not find any. So now I have been and now Iam back and here are my comments
We stayed in there beach house cabana I beleve it was #6. It was a bit sparce on furnishings but the air conditioner in the bedroom worked great and the bed was comfortable. They also have bikes and kayaks free of charge for guests. This establishment is located very close to the split where every one swims and hangs out ont the sea wall. All in all I think we made a good choice.
We also went snorkeling with Carlos, a very good trip.
