Was dreams punta cana previously sunscape? I think I remember reading something that they remodeled to be a dreams resort. If so, I was there before it was dreams on vaca in March 2007. It was a gorgeous resort. I did see a wedding party taking photos when I was there and it was absolutely beautiful. Beach was great, quality of food, service and rooms (we just stayed in the basic room, I think all have balconies or terraces) was top notch.
For anyone traveling to the DR, I would reccomend booking some type of organized shuttle transportation in advance instead of getting a taxi at the airport. It's a long ride through some not so great areas. Especially with the recent eathquakes in haiti, you don't want to take any chances. Also, I would strongly reccomend any guests to not rent a car to drive to the resort. Advice from my coworker before I went there - her brother's wife is from the DR. I can give you more details if you want. Not trying to scare you, just an important piece of info to keep in mind since you and your guests will be travelling there.
