My girlfriend and I (we are in our 30s) will be traveling to Vieques for a wedding this Saturday night. We will be spending only 1 night in San Juan and would like to make the best of it. What is a good area to stay in terms of nightlife? We'll probably want to go out to dinner somewhere fun and then probably grab some drinks afterwards. We are open to taking a taxi to get places but are looking for an area of town to stay in with just a fun nightlife atmosphere. Is viejo San Juan a good idea? Is the Carolina area better? We'll likely book our hotel tonight.
