I can't begin to count the number of dinners we have had at 1900 Park Fare. Last one was this July. Every time we have gone, it has been Cinderella, Prince Charming, Lady Tremaine, Anastasia, and Drizella. It is the only character meal that our daughter (now 10) still insists on going to every visit. I have opined on numerous pages that this is the best character interaction anywhere at Disney and still feel that very strongly.
On a visit back when our daughter was quite young, she wore a Cinderella costume. The stepsisters both complained to her quite loudly that no kids ever dressed as them. So, the following two years, my wife made her Anastasia and then Drizella costumes to wear. Those visits (and a third holiday visit where she wore BOTH costumes with a mid-meal costume change) are some of our favorite experiences at DW. I hope they keep that group of characters so that generations to come have the chance at similar experiences.
