Wow, thank you for all the sugggestions. Several places that we checked only had the most expensive rooms available on such short notice. We did manage to get a room at Mata Rocks and they gave us 10% off when they heard our sad story. Free bikes, free breakfast and an ocean view! Plus it looks like we're going to get our deposit back on Caaribe Island. I am really looking forward to exploring Ambergris Caye. Thanks again.
