I think that the "master planning" for Disneyland was to create an amazing family experience.
Other than WWOHP I don't know ANYONE who would go out of their way to go to USO...or USH for that matter. So you could debate the "master planning" all you want and who's layout is better than the others but all that is null and void when it comes to what the park can generate as an experience. I'll take DLR
I'll send you guys a postcard from DLR to USO...oh wait, does USO have a system like that?
