How many people would actually go visit this theme park? I know a lot of people who still have an interest for the past may still go but I cant imagine a lot of kids wanting to go there..
It was a theme park...with rides. As noted above much the ride designs for America were finally used for DCA...Soaring was originally convinced for America, California Screaming was originally the State Fair roller coaster, and Grizzly River Run was originally Lewis and Clacks Rafting Expedition. There were two or three more coasters planned...including Dogfight! (which some believed became Rock'n'Roller Coaster), civil-war theme steam train, etc. These are all now many of the most popular rides in their parks. If they had built it, it may have been the only Disney Park for years that had
one inverted coaster, let alone two or more.
As for the history, its location was a big deal. Tourists flock to Washington
for history (monuments, Smithsonian, National Archives)
; Civil War battlefields are big tourists draws in Va. (Manassas, Appomattox, Wilderness), Md. (Antietam) and Pa. (Gettysburg); Anheuser Busch built the Va. Busch Gardens in Williamsburg for a reason, Colonial Williamsburg is still one of the biggest tourists draws in the Mid-Atlantic. Epcot's World Showcase, which is nothing but idealized historical-fiction for the various countries, still seems very popular; DCA's 1920's Hollywood; DHS Hollywood Blvd; Liberty Square; Orleans Square; Main Street U.S.A; Fountierland are all idealized historic themes...nothings says it had to be more authentic than those.
In theory, there was something for everyone.
