We (2 couples, mid 40's) will be spending a week in a friends villa near San Isidro. He has made some recommendations, but we are looking for some input on things to do. Should we rent a car, or hire a driver? We have transportation arranged from the airport already. How far to the best beaches? We plan on doing a horseback riding tour into the rain forest. How close to the nearest zip line tour? Where would we find some kind of night life? Casino? Restaurants? Any other info would be appreciated.
