The only character breakfast we will take time away from the parks for is 1900 Park Faire. The food is SPECTACULAR!!! The service is top notch, and the characters are wonderful... and you will see old favorites, such as Pooh along with others not found in other places... Mary Poppins, Alice in Wonderland, Mad Hatter...etc.
Usually we do this breakfast on a day when we are either not doing the parks, or are doing them later in the day. It is very convenient to take a bus from your resort to the MK, hop on the boat launch (a great ride in itself) and eat. When you are done, the next monorail stop is the MK!
