My best suggestion to those with reservations for later in the winter. Sit tight for a few weeks. I, too, am going in February (can't wait either and the snow hasn't even arrived yet!).
After all, the rest of Belize is still open for business so if Placencia doesn't get things done in time (although February is a long way away), well, here are other areas still in Stann Creek District that are open for business.
