On of the positives with staying in FOD is the owner Billy can give you direction and answer your questions. I believe Playa Dorada which is right across the road has a nice golf course and a casino. Sosua is a relatively short cab ride away.
If you want to take a few hours away from your festivities one day and do a little siteseeing, take the cable car ride to the top of Mt Isabella in POP. That, too, is a short cab drive away.
