We did all three events last fall-- CRT Breakfast, 1900 Park Fare Dinner / Cinderella's Gala Feast, and Akershus.
Best princess interaction was at Park Fare-- Cinderella spent a good amount of time with us, and actually sat down on the floor to talk to DD (3 at the time.) Our niece was asleep and Cinderella posed with her in such as way that it looked like she was holding her. Now-- I am sure that it could be different if park fare was crowded, I'd say 1/3 of the seats were empty when we weere there. Prince Charming was also GREAT-- dancing around with the girls, etc.
Akershus was just so-so. We were there for dinner and not crazy about the food or the entire experience (LONG wait, slow/ uneven service.) I could see where that one *could* be great, but that was not our experience. DD doesn't even remember it.
The castle for breakfast was awesome, but more for general ambience than the interaction. We did see Snow White, Aurora, Mary Poppins (?!), and Fairy Godmother in addition to the pictures with Cinderella. (No real interaction, just pictures and signing books.) The photo package was GREAT-- the photo was lovely.
So, hey-- go for both the castle and Park Fare-- they are both great and pretty different. We are doing them both again in... 12 days!
