I checked out the updated tourism data for Belize today and figured I'd share this table with occupancy by region. It's based on rentals, so not a full look at all properties including owner-occupied, but thought the numbers might surprise some folks. I highlighted the areas where foreign occupancy of rentals was greater than 20% of available rentals.
