I'm in the same boat. I'm getting married @ Sunscape on October 5th. I was pulling my hair out until yesterday because the Sunscape was incorrectly on the list of closed resorts.
I and my travel agent have both been in contact with Signature Vacations (our carrier), the Dominican Tourism Board, and the hotel itself (including my wedding co-ordinator Danny Ortega and the PR department) and both say the hotel is up and running, never was closed, and the damage has been cleaned up and repaired.
I'll believe it when I see it of course but I've been told we're good to go for our October 2nd departure.
Hope this reassures you.
