Ok so I don't know the exact answer BUT, I'm getting married on the Dream. We have a small guest count and are planning on reserving the private room for the night of our wedding! I will be in my dress!
I would email Meredith but I don't see why that would be an issue! If brides have worn their dress into the main dining rooms, I wouldn't see an issue with Palo!
Hope this helped
