We will be going to PR in August and we want to stay at La Concha. Based on what we have read, we only plan to rent a car on days we went to venture out of the San Juan area. My question is about nightlife around La Concha. We would like to go out a couple of nights for drinks, salsa dancing etc. instead of just going to the hotel lounge every night. What transportation is available for this? Is it the type of place that you walk to the bars/clubs and then walk back or are their cabs available? We don't plan on getting hammered on nights we are out on the town...just a couple of drinks and dancing. Do you recommend renting a car for the entire visit in this situation? Thanks for your input!
