I did both 1900 Park Fare (for dinner) and Askerhaus (for breakfast) with my niece, who was four, last fall. We really liked both of them (in fact we did CRT too and we liked 1900 Park Fare better).
At 1900 Park Fare it was Cinderella, Prince Charming, Lady Tremaine, Druscilla and Anastasia. I thought they did a great job of being nice to the little ones. My niece thought it was great that Anastasia told her that her dress (she dressed in her Cinderella costume) looked better on her than it did on Cinderella.
At the princess breakfast we had Belle (free picture), Aurora (Sleeping Beauty), Snow White, Jasmine and Mulan. Again, character interaction was great and my niece loved seeing all the princesses in one spot.
If you just want to get a lot of princesses in at one meal I would do Askerhaus. If your daughter loves Cinderella (like my niece does) I would do 1900 Park Fare.
