Deal hunting...Costa Rica

In preparation for my upcoming trip to Costa Rica, I am feverishly hunting for deals and trying to plan out my itinerary, while also trying to fit in some less touristy destinations. Not as easy as it sounds, since Costa Rica is a tourist haven. It's amazing how most of the hotels are owned by gringos!

I've listed below some of my finds, just hotels so far. I prefer to find my "activities" deals on the ground.

Arenal:
Treehouse Hotel
Observatory Lodge
Cerro Chato Eco Lodge

Monteverde:
Terra Viva

Osa Peninsula:
Las Coletas Lodge

To get to Osa Peninsula from San Jose:
Osa Shuttle - Roundtrip flight usually costs upwards of $200, whereas taking this private shuttle is less than $100/person
