There are no princesses at the CRT dinner. Your group has its picture taken with Cinderella in the lower level of the castle prior to being seated. There is a small show with the Fairy Godmother and Mice from Cinderella during dinner and if I recall the Mice move about during dinner.
Oh, I am a 33 year old man (boy at WDW) and I enjoy the food and character interaction; and my fiance loves Cinderella so it's awesome for me to see her take in the entire event.
