I think you and your buddies will have a fun time at BocaChica, Boca Chica is closer to the Airport than Santo Domingo is. They say you fly into Santo Domingo, but really you are flying in to San Andreas, which is right beside Boca Chica and about 15 minutes from Santo Domingo. If you want a real good web site go to
www.bocachicabeach.net you'll find this site very informative. If your buddies want a beach, SD does not have one, but if you stay in Boca Chica....access to the Capital is very easy and at the same time you'll have your beach! Good Luck. If you need any more info your more than welcome to e-mail me.
