I have a couple of days free next week and would like to get away from San Jose. Thinking about Arenal, Coffee Plantation, Snorkeling, Zip Line, etc. I have prepaid for my hotel, so would need to come back to the hotel vs. staying out for the night. Can someone recommend a couple of day trip ideas? I would need transportation but would consider a car rental for a day (I think about $50) or bus or tour. Probably will be alone, although I may be able to find someone to go with me...that would reduce the car cost per person! Thanks.
