I have not experienced the new CRT dinner menu, so I can't comment on that, but I will say that it DEFINITELY sounds like a 'special' birthday to have breakfast with the Princesses in Norway and dine in a Castle for dinner! Sometimes a character will appear in the lobby while you're waiting for your table there, too! (Or at least that's how it used to be...I met Cinderella, Belle, and Aurora in BLUE there on separate occassions years ago.)
Just because I can't say enough good things about the breakfast in Norway, here's some more info about it:
~The meal was a pre-set menu with a fixed price and we had potatoes, scrambled eggs, sausage, bacon, warm biscuits, and cinnamon rolls. Everything was delicious and served just right; we also got orange juice and coffee.
~Characters are always subject to change, but Snow White, Aurora, Belle, Jasmine, and Mulan make an effort to be there for breakfast. (I heard that recently Ariel has been available for photos with guests waiting to be seated for breakfast as well.) I hear that lunch and dinner usually features Cinderella, Aurora, Ariel, Belle, and Jasmine. If a Princess is swamped with Royal duties, Mary Poppins, Alice, or Wendy will sometimes fill in for her. I have also heard of rare occassions where Pocahontas or Esmeralda was there (though I only heard of each of them being there once), and I hear that sometimes Aladdin accompanies Jasmine. (The character list is based on discussion with many, many, many guests who ate there; I worked in World Showcase and "eating with the Princesses" was a frequent answer to "what was the best part of your day?" and I always liked hearing who was there.
