I have never been to 1900 Park Fare but have ressies in March. I will say that CP is one of our faves! We do this one every trip. Good luck with your decision!
I have never been to 1900 Park Fare, but am thinking about going in Oct. I love the breakfast at Crystal Palace, but think I would like the characters better at 1900. I may end up doing both.
An 8:05 reservation at Crystal Palce on a day the park opens at 9 is wonderful! You can take a few photos in front of the castle in an almost empty park.
A late, 11:00 breakfast at 1900 Park Fare is great after an extra magic morning in MK. You are leaving the park just as it's getting crowded
