Me amd my boyfriend are going on our first vacation to PDC next week. We are staying at the riu palace riviera maya and I understand that there you cannot exchange at the hotel. It is all inclusive so we are not planning on spending any money on dinners or anything besides tips, souvenirs, and possibly excursions. How much money do you suggest we bring? Can we tip our bartenders and hotel cash in USD? Can we buy our souvenirs in town and from the hotel with USD? if not, where do you think is the safest place to exchange from USD to pesos?
