Our family will be renting a car and driving to Puerto Viejo for 6 nights, then we are thinking about going to Arenol on the way back to San Jose. We could leave in the morning and drive there hopefully by mid afternoon. I like the looks of the Ecothermales hot springs. We would spend one night somewhere in the area, and have the next day to enjoy zip lines, canopy tours or whatever. We would head back to San Jose that evening for an early flight the next morning. Does that seem doable? Any suggestions of budget place to stay that will rent for one night?
