We did it in November. It was just ok. Chef Mickey's had much better food. Having said that, the dinner was a better option for us than doing the CRT breakfast. If you want to see Cinderella and she is the priority, 1900 Park Faire is worth at least one trip. We did CRT for breakfast once and thought it was just OK. I guess the hype gets you. We do enjoy going there for dinner.
We did find Cinderella in Mickey's toontown fair. The character meal was worth doing at least once. We really like the Princess Breakfast in Norway. The food is great and so is the character interaction. It was the only place we found Snow White.
Our family just loves Chef Mickey's and we do dinner there every trip.
