Thinking about a trip to Costa Rica and don't know anything about the area. Just wondering if anyone has suggestions on which town to stay in for first time visit? We love the beach and some nightlife. In the past we have preferred Mexico over Caribbean as far as the "vibe" goes if that helps in identiying what we enjoy. We would also like to be able to get to some of the waterfalls and natural attractions of Costa Rica. thank you for any advice you have.
