I heard there is a Bus you can take to go to Capitol city and it leaves you infront of your capitol city hotel. It costs about 70 pesos. anyone know about this? or any other reasonable transport from PC to SD? Thanks
From Punta Cana to SD will cost you about 250 pesos.
First take the Espresso to Higuey for 70 pesos and there you get on the Espresso to SD for 140 pesos. The endstation is Parque Enriquillo.
With the Expreso Bavaro or Punta Cana you'll spend RD$230, and it'll drop you anywhere along it's route to it's final stop which is close to the Nacional Supermarket on Maximo Gomez. Unless you get a free ride, there's no way you'll get from Punta Cana to the Capital for less than RD$200.
