I emailed my TA about this very topic. We are on the June 12 Double Dip. She said that the "dress up night" will be the night we are in Royal Palace. That doesn't sound right to me because I thought a "dress up" night would be one night for the entire population of the ship to dress up. I have decided to start reading for clues on upcoming trip reports, and if I am still not sure in a couple of months, I will call DCL directly. Cass, what do you think?
