The easiest and simplest solution is to take Tracopa bus from the San Jose bus terminal. It goes to Uvita (and also one goes daily from Uvita to San Jose). Its cheap, but a long ride. You can also pool with one of the many shuttle services which go down the highway in Puntarenas, to Uvita. If you land in San Jose during the day, its highly likely that there will be some shuttle services heading to the area, but you can also just do a web search for one and book one ahead of time. This should cost about $40 - $75 USD. There is also the option of searching for a private shuttle service for yourself and companions, this can cost like $120 and up. Lastly, there will be loads of taxis at the airport, and you can bargain with them. They might want to charge you up to $300 USD, but that is just because they assume youre a naive tourist. If you pool with a few other people, you can talk a taxi down to like $30-40 a person (to go to Uvita... less if youre going somewhere closer like Jaco). Once you get to Uvita, there is a supermarket across from the main bus station. There are usually several taxis hanging out there, especially during tourist season. They will know how to drive to Cabinas los Laureles, though, its within walking distance of the bus stop. Again, some taxis might take advantage of your lack of knowledge and charge you $10 USD, so negotiate before getting in the car (its like a $2 USD drive from the supermarket).
