Glad you picked your resort
I agree it was the most frustrating thing. I know some people are able to go out to the DR and look around and then pick a resort that way, but unfortunately that wasn't an option for us because we really couldn't have been able to pay for 2 trips this year.
I got some good advice from my cousin who is a travel agent - she said first and foremost, email the WCs of the resorts and if you don't get prompt responses, then forget it because this is the person you need to talk to about planning your wedding when you can't be there to overlook anything.
That was how I ended up with my resort.
I knew I wanted a 5 star, no exceptions, a good price for the wedding package and group rates, my date was very important to us - so a few of the hotels we looked at didn't even have our date (I think our first choice was Dreams) so we ended up with Gran Bahia Principe Punta Cana and I'm actually really excited after talking to other brides on the forum and other people that went there for their vacations!
