If you are just looking for a character breakfast we have done: Akerhouse (twice), CRT (once), Crystal Palace (twice), and 1900 Park Fair (once). I really enjoyed them all.
Akerhouse: The have a cold buffet and then the rest of breakfast is served family style. I love their potato casserole (yummm)! But I find the character interaction here a bit rushed. I do like that it is only 1 TS credit on the dining plan and you get to see 5 princesses here. We went last December and saw Belle, Snow White, Aurora, Cinderella, and Ariel. Here is also get a picture included in the price of your meal.
1900 Park Faire: This is a buffett at the GFR. The food was good, they had beautiful heavenly strawberries that my children ate their weight in. We saw Alice, The Mad Hatter, Mary Poppins, Pooh, and Tigger. My biggest drawback was the travel time to and from the resort, but we would do it again. My family loves these characters.
We went to CRT for breakfast once, but it was way back on our honeymoon, so I don't think my review would be very good now. It is family style and these days hosts the princesses. We had dinner here in December and really enjoyed it.
Try the Crystal Palace at Magic Kingdom. It has Tigger, Pooh and piglet. The food is really good as well. If you can try and get an 8:00 ressie that way you can see the park empty and still be done in time for rope drop.
But my favorite is Crystal Palace!! You get to see Pooh, Eeyore, Piglet, and Tigger. The character interaction here for us has always been fantastic. The food is great! I love the build your own omelet station. But my absolute favorite favorite thing is securing a before park opening ADR time and getting to see and take pictures of my family on Main Street and in front of the castle with no one else around!! Truly magical.
Good luck! There are lots of choices out there. I know these places also have some AK (Donald's Breakfast), DHS (Playhouse Disney Breakfast), Polynesian (Lilo and Stitch), Cape May. I am sure I am missing a few.
