Welcome Tania! I'm considering Dreams Palm Beach as well! Of course, it's hard to know much about it since it isn't open yet, but the Dreams resorts are so reputable and I've heard Palm Beach is on a terrific stretch of beach. Plus, the rooms look adorable. I put in a request for a Sept 09 wedding but haven't heard back yet. We'll have to keep each other posted!
As far as La Romana, I think I read that you would still fly into Punta Cana and that it's quite a distance to get to the resort - maybe 90 min? I could be wrong...
