They do have an alternative to the egg breakfast, I believe it's granola and yogurt (at CRT's-at special request), not sure about PSB, they were a little difficult about any alternative the first time we went there. Both also serve muffins, crossiants, rolls & fruit. CRT's have a pancake breakfast for the kids and PSB has french toast sticks on the main platter.
There is also the 1900 PK Fare Character Dinner. Cinderella, Prince Charming, Fairy Godmother and the mice, Suzy and Perla are there. I haven't been to that one yet, lots of mixed reviews but a chance to see a princess at dinner.
