Expect fun, good food, and excellent service. CP is my favorite character meal.
When you arrive, you'll check in outside. After a few minutes the CM's will call your name, and you'll be led to your table. When your server gets your drink order, you can dig in to the buffet.
Ask the pancake chef for Mickey pancakes for the boys. There are plenty of food choices, but they cater to children very well, with fruit and cereal choices, mini donuts, muffins, character waffles, etc.
There are four characters, generally, Pooh, Piglet, Tigger, and Eeyore. One (last year Piglet, year before Pooh) waits by the food service area for people to come up and take a photo. The other three come to each table and visit with your group. Have the cameras and autograph books ready! They ask that you don't interrupt other groups as they are visiting with the characters.
If you are waiting too long for a character, or just missed one as you were seated, let your server know, and they'll bring a sign to your table that alerts that character that you've been waiting/missed.
Don't miss the beautiful dried flower arrangements as you enter the CP.
Have a magical time!
