Since she'll only be 3, I'd say Norway. It's a tiny bit cheaper but still packs the punch of many princesses. Belle is the star of the show and you'll get a picture with her as part of your meal. Cinderella does not appear here however so if that's her favorite then Cindy's Royal Table might be better and then you'll get a picture with her. Reservations ADR's can be made 180 days out from either the date of your arrival that day in the park or 180 days out from your room reservation date if your staying on property. Plus if you stay on WDW property you can make ADRs up to ten days of your stay. It's easier to get a reservation at Norway but for the time of year you are going hopefully you could score one for Cindy's .
