Dont know if you are interested in any excursions, may want to try the Outback Safari or Bavaro runners. Also, there are day trips offered from Bavaro to both Saona and Catalina islands, both which I highly recommend.
Not far from your resort is the small shopping complex, Plaza Bavaro if you are interested. You can also walk down the beach...make a right onto the beach, walk about 30mins and you will reach the small town of Cortecito....make a left down the beach and a ways down,there is a small market with beach vendors.Enjoy!
