Thanks to everyone for the advice I've received thus far. I think I have settled on Arenal, Monteverde and Osa/Bosque del Cabo for our first trip to Costa Rica in December. I would love some advice on how best to organize transportation between the destinations, and what order makes the most sense. We will arrive into SJO very early (6:30 AM) and will depart from SJO early (8 AM), so will plan to spend last night near the airport. I am not keen on driving ourselves between the locations so will plan to arrange a driver, and do plan to fly to Osa. I think I would like to have either arenal or BdC be our last stop (not monteverde), but can go otherwise if the transport makes more sense. thank you in advance for any advice!
