We are really big fans of breakfast at 1900 PF. The characters are usually (of course they are always subject to change) Mary Poppins, Alice, Mad Hatter, Pooh and Tigger. We love the variety of characters (all the stories take place in England if you couldn't figure out what ties them all together), the interaction with them and the breakfast spread there is very good. We love getting to MK for RD and then head out to GF for one of the last ADR's of the morning (usually around 11:15 or so). It gives us a chance to get some MK touring done, collect a FP or 2 and then have a nice quiet character meal (the meal starts out loud but the restaurant empties out pretty quick). Then by the time we head back to MK our FP's are in affect and we are rested from the late morning break and feast.
CP is nice if you are looking to get into MK before the park opens, which is something everyone should try once. There is nothing like an empty MSUSA to get great pictures of the castle, the partners statue or the train station. Besides that we really don't care for CP in general. TH at AK is another great character meal to help you get into a park early for some great pictures of the Tree of Life.
