We were in the
bay that straddles the border with Belize, and the capital or main town of the state"Quinton Roo?" was on the west side. Sorry that I don't have a map. I have read that they have now establish a guide service out of that town.
My understanding is that some of the roads have now been improved. They were terrible then.
Re wind...the best time not to get wind is July and August and the further you get away from that, the more likely that you will have bad weather. I have a well-traveled friend that will not go to the Carrabean until May, and preferably late May. I was in Ambergris Is, Belize lin early May last year and had a lot of wind. However, the weather was ideal earlier in April around Easter. I'm going back to Ambergris this May but mid-month
