You were lucky. When we went down we first walked to the middle elevators. The line was past the atrium and we got in just after Rudi's. It went all the way into the dining room, turned around and then all the way back down deck 2 to the theater. As we were coming down towards the theater, the line had grown all the way down to Billboard. It moved but was still frustrating as clearly people were trying to get into line wherever they could and not everyone followed directions. There were many people in line with their rolling carryons. People on scooters were having a rough time because there really wasn't enough room for two lines plus people just trying to walk through.
The good news was, that in spite of everything, we made our flight and are all home safely. It was a wonderful trip and I totally agree that a 7 day cruise will be a very strange feeling. Good thing my next one is 13 nights.
