We were there in October and had Belle in yellow gown as the greeter, then Snow White, Sleeping Beauty, Jasmine, and Mulan in the dining room.
In response to an earlier poster: YES, you do get to take photos with each one. The official Disney photographer takes your child with the greeter princess before the breakfast. The others come around while you dine.
We went there for the dinner in March 2005, and the princesses were similar, but the greeter was Ariel in her blue dress, and then Belle in her blue dress, Sleeping Beauty, Jasmine, and Mulan in the main dining room.
I personally preferred the breakfast foods, and so did my dh and my dd, but your mileage may vary.
