I can't answer for the three day Wonder, but on the four day Wonder the menu selections for Monday were from the three rotational menus. For example, one of the appetizers was the escargot from Triton's. The fish was the Grouper from Parrot Cay. The pasta (with turkey and prosciutto) was the one from the Animator's Palette menu. There was a rib eye steak also, but it did not seem to be like the one in Parrot Cay. There was also a salad bar, although you could order a prepared salad like the ones in the dining rooms. I don't remember about the deserts. The menu looks like it is printed that day (it's just a simple list on regular paper), so that may explain why it's never been scanned for the boards.
We also did the BBB dinner on the Magic. It was the exact same experience,i.e., selections from the three rotational menus, but I don't remember if they were the same ones as on the Wonder.
