We have had good experiences with CP.
The only thing you may need to think about is whether a breakfast in-park meal is likely to be worth it. This depends on what sort of experience you expect, but when you take eggs, dairy and gluten out almost all of the items they work with are off the table. I know it's been said before that Tusker House is the only place in the parks that will do allergy waffles that are not Van's- Van's have soy.
You have to be ok with the reality that you might end up with essentially a plate of fruit and bacon. We have had extremely hit-and-miss luck with buffets happening to have a Babycakes donut around, but if it's an option you may be happier going with a lunch or dinner. Another work around is going for a late enough breakfast sitting that they may pull out lunch ingredients for you.
If you want to end up with safe waffles or pancakes I would contact special diets and ask specifically if they can do the allergy Mickey waffles, I think they did long time ago and may have stopped, but don't quote me on that. But- if a plate of Mickey waffles, bacon and fruit will feel like a let down, breakfast at a park buffet (excluding TH) may not be your cup of tea.
