My current plans for early March look like this:
SJO to Arenal
Arenal/La Fortuna - 3 nights
Monteverde - 1 night
Tamarindo - 3 nights
Santa Teresa/Montezuma - 4 nights
Manuel Antonio - 3 nights
San Jose - 2 nights
San Jose needs to stay 2 nights, but the rest is pretty flexible. I like the idea of all of these places, but am not necessarily set on the amount of time. Ultimately I think I'm trying to decide about Tamarindo and Santa Teresa/Montezuma.
Is 3 nights enough in Tamarindo? And is 4 nights too few to split in some way between Santa Teresa and Montezuma?
Things I care most about: meeting people, attempting to surf, hiking/swimming near water (waterfalls), and trying to find a balance between nightlife with relaxation.
