CRT = Cinderellas royal table.
HV = Hollywood and Vine. They have two different sets of characters. Breakfast and Lunch is the playhouse disney characters while dinner is Minnie, Mickey, Goofy, Daisy, and Donald.
Which 2 to pick depends on who your daughters like. Chef Mickeys have Mickey, Minnie, Donald, Goofy and Pluto. You could also do Ohana breakfast which is Lilo and Stitch, Mickey and Pluto.
If you can I would do a Pre Park Opening breakfast at Crystal Palace which has Winnie the Pooh characters. We just did this last week. It was awesome walking down main street with not many people there. We got great pictures in front of the castle. Definitely should try and book this one.
