Just beginning to plan a possible trip to Costa Rica in late December/early January. I've been browsing the travel guides, but have a general question: Which of these 2 areas would you stay in, given the choice: in el Roble in Puntarenas, or in Playa Arenilla in Guanacaste. (both are on the beach). We want to be close to hiking, rain forests, zip lining, etc. but didn't know if one location was better than the other for this. Thanks so much!
