We had dinner there last Tuesday, the 11th. My neice (4) and cousin (5.5) was with us. My neice loves Cinderella and my cousin was an Ariel fan (at the moment - she changes her mind every year). Each of the characters are introduced (as what the PP stated) and they make their way around. The prince usually is already in the room, when Cinderella gets introduced. When he hears her introduced, he makes her way to where she enters and does a who ceremony thing where he greets her, kisses her hand. Then he goes back to greeting the diners, and Cinderella starts making her way around. They stop for a few minutes when their music comes on to do a dance with each other, then dances with a few of the kids around them.
The Stepmother is very good... never once broke character. My neice was dressed in her Cinderella gown, and the stepmother asked why she picked that dress, wasn't there anything better when she got that... but at least she looked better than Cinderella. Drizella wasn't as colorful/funny as Anastasia. My neice and cousin absolutely loved her and thought she was the funniest of them all. Anastasia would jump up on a chair and sing Hannah Montana. When she came around to our table, my neice who is a big Hannah fan, asked why she sand Hannah Montana's song... Anastasia just replied "didn't you know I taught Hannah everything she knows."
Highlight for my neice was Prince Charming. He interacted with the table and was charming. My cousin refused to get her picture with him... especially since she was in her Ariel costume and "didn't want Prince Eric to get mad."
I'm not sure if PC shows up at the CRT at MK. They don't have the Photo package like in the castle though... but there is alot of opportunity to take pictures with the characters when they come to your table... they didn't make it feel rushed at all when they came around.
