The monorails don't really have any Disney theming built in like Mickey-shaped windows. Yet they've become their own kind of thing, with each having a unique color stripe, nice views, “¡Por favor manténgase alejado de las puertas!” Maybe it's nostalgia and memories that seperates WDW monorails from others, but whatever the reason, I don't feel like the monorials are generic.
I worry that the gondola cabins will struggle to stand clear of being generic. Unlike monorails, the constantly pass by, and each one won't have a unique color pattern, I'm sure. So there's no anticiaption guessing when or which one will come. Maybe my concerns are silly but I wonder if, 20 years from now, we'll see the gondolas as something magical, something special.
