Isn't that funny?!?
Your routine was exactly my family's routine in the 20th century! Pirates first, slight backtrack into Adventureland for Jungle and Tiki Room, and then on with the Clockwise show. That's just how it was done. You had to time it so you could be in Tomorrowland after sundown, because that's where all the action was and where you wanted to be at night. I'd forgotten about the Subs rule too, so yeah, that was another reason why you had to be in Tomorrowland at night.
Fantasmic! in '92 began to mess that up a bit, but it still held for a few years into the 1990's. Once I had an AP and was visiting regularly by the time Indy opened, the whole Clockwise Route was all kind of falling apart.
I imagine it's a concept that's long gone, or anyone who didn't visit in the 20th century wouldn't even consider.
