On the seven-night cruises,they have photographers set up all over the atrium and by the Walt Disney Theatre all night on formal night and you can choose which backdrop you want and take more than one if you want, at no extra charge. The photos will be available later at Shutters, 8x10 for $19.95, and they are not part of any package, though I bought five or six and they threw in an 8x10 of the ship all lighted up at night and a portfolio that holds 2 8x10s. The photographers are also available at other times with backdrops set up (dd and her new best friend took a set of pics together with a stuffed Winnie the Pooh, don't know if this was with the kids club or not. She begged me to buy it, so I did). You can also set up an appointment to have photos taken at other times as well.
I wore a beaded black blouse with georgette trousers, the kind that has panels that make it look like a skirt too.
