there are a lot of resorts in the Punta Cana area that have private receptions. I'm getting married at the Paradisus Palma Real, i have 5 or 6 different location choices that are private. I'm having my ceremony on the beach but they keep people away. you could also have it at the gazebo. the paradisus punta cana also has the same private receptions available. I know i received info from the Melia, Iberostar, and Dreams in Punta Cana and they all had private receptions and many areas for ceremonies. When i was looking at resorts i emailed each resorts wedding cordinator and asked for location choices with pics, reception packages, reception location choices with pics, menus, etc. and most will get back to you in 2-3 days with your options.
