That . . . seems anecdotal. I can’t picture that there was ever a mandate that transport attractions have to be D tickets or vice versa. Besides, Storybookland and the Peoplemover are, in truth, no more transportation systems than Pirates and The Haunted Mansion. Despite the Peoplemover being a working prototype of a transport system and themed to one in a working future, you still get off where you got on like most rides, which can also be said of the Steamboat despite being a beautiful illustration of a real-life transport system. So I don’t know that this idea lends any weight to the thought that Toy Story Mania must fall either above or below a D-Ticket level. That seems manufactured - interesting coincidence though, and one I never noticed.
It’s true that attractions have and did move up and down letter grades, but I don’t know that this should apply to Toy Story Mania - it seems to have mass appeal, but I think it’s worth wondering aloud if it’s insane popularity is in some way amplified by the fact that the park has for so long not had another attraction without height limit geared towards younger guests (if still enjoyable by the whole family). It seems to sit more naturally at DCA where there are multiple experiences of similar caliber - it draws a line, but not to the extremes of DHS. I’m curious to see if the opening of Toy Story Land will ease Mania’s line or exacerbate them; more attractions suited to the same audience, but situated in the same land which is being promoted as the big new thing. Will more people be drawn away from Mania towards the other, newer rides, or will people be drawn to the land and Mania by extension? I picture that the decision to expand on the Toy Story présence in the park was driven at least in part by the popularity of its first attraction, but whether that takes heat off or puts heat on it will be interesting to see.
Beyond that, I personally still have a problem calling it an E Ticket in a park where the Tower of Terror, Rock N’ Roller Coaster, Star Tours, and the former Great Movie Ride make/made their homes, to me Toy Story doesn’t sit comfortably on the same shelf as those expansive experiences and by design was not meant to. I do think the context of the park does or should dictate a little here - especially with Falcon, Alcatraz, and Mickey on the way, which will no doubt make Toy Story look like less of an E Ticket than ever - Either the park then has 7 E Tickets and nothing meant to sit at the D level, or Toy Story is a smash hit D in a park with several highly qualified E’s. I’m more readily inclined to accept the latter.
EDIT: My phone keeps wanting me to say Tony Story Mania, which sounds like a different experience entirely.
