None of the others you mentioned need a cc deposit. The only times I've had to give my credit card were for CRT, Princess Storybook meals in Norway, California Grill, Fantasmic Dinner Packages, and the dinner shows (Hoop de Doo, Spirit of Aloha, Mickeys Backyard Barbeque). Have fun planning.
Wanted to add - I've been following your threads about winning a trip and staying at the Poly. Kona Cafe if one of my kids favorite places for dinner. They just love the "Kiddie Kone" dessert and the sticky wings.
