My husband and I have 1 week in Costa Rica in August. I think I've finally narrowed down where I want to go. I would like to split the trip between Arenal & Montezuma. We can fly into either San Jose or Liberia. Any suggestions on where we should fly into and how we should move from one place to the other. I don't want to spend too much of our too short vacation on the road. So if it makes sense to do any of the little flights we are open to that. Any info is greatly appreciated.
