My daughters and I will be visiting Tikal in April and we're trying to figure out the best way to get to Caye Caulker. We we're thinking about taking the shuttle from Tikal Inn to SI and fly from there. But there is no direct flight, it goes to Belize Municipal airport first and the connections are only 5 minutes apart, so very tight. How long would it take to drive from Tikal to the boat dock and then we could take the ferry? Any other ideas?
