I returned from Costa Rica in February and can't stop obsessing about it, so now I'm planning my next trip for Jan 2013 with my husband. My daughter and I stayed in the La Fortuna area (volunteered at Proyecto Asis) and Manuel Antonio. I want to visit both Puerto Viejo and Osa on my next visit for 10 days. I'm not sure how to do this though without renting a car. Would we take a shuttle to and from Puerto Viejo from San Jose, and then fly to Osa? I'm thinking of Banana Azul and Bosque Del Cabo. Any suggestions?
