Thanks for all of your input!!
We will watch out for the "transporters" as we will probably do the buffet those evenings!
I noticed a lot of casual dress in horizon court, pool areas, casinos, and on the decks during the formal nights. Personally I was disappointed by the formal nights becuase I expected that there would be more things to do all dressed up. I found it pretty boring, and went back to my room, changed out of my dress and enjoyed the rest of the evening in my casual clothes!!
(We found the same to be true on a Royal Caribbean cruise!)
