Just FYI, I went to Costa Rica with GM 15 years ago. The hotel was like a prison; it was nice but I was afraid to go near the fence. Outside the "wall" was like a slum. Poor folks were living in corrugated tin shacks. I felt ashamed being there.
Drank bottled water and sodas for the whole week. Last day there, had a Coke with "local" ice.
Got dangerously sick the next day on the way home. 5 months of intestinal issues and clear liquid diet. Lost 30 pounds.
Maybe Scotland or Alaska or some such, but I'm never going to a third world country ever again.
