Beaches
The Ibersostar on the north coast has a poor beach even by north coast standards! Gotta head out to Sosua/Cabarete/Caleton/Grande....there are some sweet beaches up here.
For the south, you need someone else besides me to help you! Check another thread that asks about getting from LaRomana to Sosua....this has some costs for the trip to LaRomana at least...
Only been to PC once, from SD took about 3-4 hours if I remember correctly. I paid RD$1000 for private taxi that took us on a tour of SD, to LaRomana, Altos de Chavon, and a couple other stops along the way to PC Bavaro.
Don't know if that helped or not!
