Best to fly out of Newark
Prices are ridiculously high during the vacation season. Why rent a car? For the cost of renting a car and insurance, you could have an extra daily piece of puta. Take buses, guagau's, and taxis. Just watch your wallet when a chica slids up to you in a public transport. I have been pick pocketed twice of phone and a little money. Otherwise than that, I have never felt unsafe here. Check into the New Garden, if no room there, they have a nice counterpart 100 yards away. The beaches are in walking distance or you can take a motar, motor bike, and the operator will take you any place. Ask the price first. Oh! Continental flies only on a Tuesday and Thursday. Check on this. Flight is direct and lands midday. I have lived here, not in Sosua, for nearly a year and see owning a car as a pain in the ass. Not only that, they drive crazy here. The food is good in Sosua, and so is the pussy. You might look into the Colibri at the other end of Calle Pisante. Almost across the street from Passions. This a good motel with lots of space and pool. No hassles with guests.
Good luck.
