My husband and I are leaving for Costa Rica on May 11th. We will be in the La Fortuna area for 6 nights with a Groupon that includes round-trip transportation to the airport in San Jose. I've also booked five nights in Quepos, and an additional 3 nights in Alajuela. I thought it made the most sense to rent a car for the MA/Alajuela portion of the trip, but am starting to have second thoughts. Our hotel (Parador) does run a shuttle to Manuel Antonio during the day and I doubt we'd be doing much driving as any tours we wanted to take have pick-up available; cab fare runs about $5 each way into town. When we go to Alajuela the one thing we want to see is the Poas Volcano but I don't know if we should rent a car for the whole time to see that.
So, looking for suggestions. I do want to stop at the Tarcoles Bridge so looks like we would definitely need to get a private driver in one direction for sure. Can someone give me some advice on (a) how much this runs and (b) some good referrals. Also, if you were in my position would you go for the rental for the whole time or something else...and if something else, what?
