Hi Amanda, welcome to the forum. I'm getting married in the Dominican at the Paradisus Palma Real. Our resort is on Bavaro beach which is very beautiful, it has the white sand with palm trees. But it didn't really offer different room options. Some of the resorts we looked at were Melia Caribe, Paradisus Punta Cana (a little less expensive than the palma real), and the Iberostar. All of them are in Punta Cana, DR. They all looked pretty nice. And they all allowed kids. Melia and iberostar looked very kid friendly. They are all all-inclusive also. A new resort just opened up called the EdenH, it looks incredible from the pics, i'm not sure if kids are allowed.
If you want any specific info on the Palma Real just let me know.
