My wife and I will be staying on Ambergris Caye 7-13 October, and we're wondering about ease and cost of travel from the Caye to Maya Ruins in the interior. I understand that Lamanai is a reasonable day trip. What about Xunantunich? Caracol? Or even Tikal (which I realize would require going to Guatemala). How would one travel from Ambergris Caye to some of these more distant sites, and how expensive would it be? Finally, is it possible for us to go to Belize CIty and just rent a car and drive to, say, Xunantunich?
