Great ideas! Here are some of mine.
Take the Diamond Horseshoe Revue (may be called something else now) and make it "Woody's Round up" with sandwiches, pizza, and western entertainment on stage. Great for boys and girls.
Turn the American Pavillion restaurant into either a buffet or market (like the Pepper Market) featuring food from all over the country. Different displays of cajun, New York (deli? pizza?) Philly steak sandwiches, Pittsburgh's Primanti sandwiches (yummy!!!) californian cuisine, maine lobster, Texas roadhouse, BBQ. midwest steaks, starbucks coffee station...you get the idea.
A space ranger character meal for boys.
And not in the parks but around the resorts...more dinner shows!!! The luau and hoop dee doo have been there forever.
Love the ballroom dance/dinner thing. The dance hall at the boardwalk would be a great place for that. Atlantic Dance, I think it's called???
I like the tex/mex idea. Maybe in adventureland, in that old terrace restaurant that's been closed forever. I can't think of the name right now.
OK, I'm done now.
