Going to Puerto Vallarta for our HM. Never been to Mexico before or any non-English speaking country for that matter. What do I need to know? What do I need to bring? How about in terms of currency? Do they take US dollars, credit cards, etc? We're staying at an all-inclusive, so I don't plan on spending too much outside the resort except for excusurions and adventures. About how much $ should I bring for 1 week? Is there anything I should bring from home because it'd be too inconvenient or costly in Mexico?
