My husband and I are trying to determine if we should fly into LIberia or San Jose, en route to see the Monteverde and Arenal Volcano areas. We thought we'd rent a car in either big city, and drive to Monteverde and Arenal areas (which one first, is also the question). Does anyone have suggestions? Is driving from either big city preferred? Or would we be best taking a chartered van tour of that area? We only have 3 days for that part of the country, then we'll head to Jaco and vacinity. Suggestions would be greatly appreciated. Thank you!
