I get to dress up SOOO rarely, it is fun to stay in my nice clothes and heels! (yes, heels!) Fun to go dancing later all dressed up. Luckily DH humors me--I think he would rather change.
Saw both on our Princess cruise last Oct.--some stayed, some changed.
I am guessing our boys will change after each meal--DD is a diva, but I will request her non-washable dresses be changed before she goes back to the kids club!
Happy cruising!
