Just came back from Punta Cana, we went one day at the Manati park, it's worth it, it's not really big, it's very nice,lots of trees, flowers. The dauphins show is good, I had my picture taken with a dauphin for $7.00 U.S. I didn't swim with them. The Taino village is very nice, you think you are in Africa! All the others shows were good too, but we found they were not long enough. They have a schedule for the bus to take you back to the hotel. You should do the tour to La Romana - Altso de Chavon, very interesting, with that tour you really see how the Dominican leave.
