1. Money. When I get there should I convert a certain % of what I bring to CR $? Also, should I only bring 20s? I heard that a lot of places won't touch US 100 bills? Should I keep most of my money on my DC?
2. Cigarettes: do they sell Marlboro in CR? What's the price per pack?
3. The water: safe to drink or no? Ice cubes in drinks?
4. Phone. Verizon iPhone won't work in CR. I can rent a world phone for 20$ from verizon, should I?
