I may have to travel from Playa Palenque to Haina and return several times. In the past I have always gone through the center of San Cristobal and taken the secondary roads. In the hope of doing it faster I was thinking of using Route#6. Does anyone have experience in doing this and is it a good idea to save some time? What is the approximate travel time? What are the best exits to use? Thanks in advance for any help.
