I will be going all around the country:
Liberia Airport to Tamarindo (Beaches)
Tamarindo to Santa Elena, Monteverde (Arenal Volcano, something else)
Santa Elena, Monteverde to San Jose (Poas Volcano, quick visit to Limon, explore San Jose)
San Jose to Manuel Antonio (Beaches? National Park?)
Manuel Antonio to Liberia Airport
I will be spending about 3 days in each place (Liberia doesn't count). How do you do this by bus (for two people)? And how do I maximize my time?
