We dined at CRT in September and October for dinner and in September Cinderella was downstairs when you first entered. In October, I can not remember her being there.
At dinner you MAY see Cinderella in the castle lobby before you head up to eat. But starting in Feb the Fairy Godmother will be upstairs to perform a short celebration with Suzy and Pearla. Cindy should still be downstairs for pics. No other characters are there though.
