I'll be coming to Belize in December, and I'm thinking of staying in Placencia, or Belmopan for the first three nights of my stay. I want to go to Tikal for an overnight, and then I'll be staying with friends in a timeshare for four nights on Ambergris. What's the weather like at that time of year? I know it's cool at night, but do I need to worry about a lot of rain? Do I need more than one book to read in case of inclement weather?
