la posada del peidra is located in el cortecito right beside my own business. you made a great choice without doing the so common all inclusive vacations. it's run by a very nice couple, they will thread you like king and queen. from santo domingo to here you have two possibilities, and both drop you off at the corner of El Cortecito 100metres from your hotel, no cab needed.
* number one is to take the so called "Expresso Santo Domingo-Bavaro", their destination station is the above mentioned bus station at friusa in bavaro, but they pass by El Cortecito, if you tell the driver you want to get out at El Cortecito they stop there.
* my prefered one is to take the expresso from santo domingo to Higuey, you find their bus station in santo domingo at the "Parque Enriquillo", every cab driver knows that busy spot with the bus stations for all directions, so they drop you in Higuey at the bus station for bavaro, there you ask the drivers which bus is leaving next for "El Cortecito in Bavaro", the bus is leaving every 20 minutes and they all pass by the corner of El Cortecito and stop there.
have fun in my 'hood
