[Cadaverous Pallor]

All of the above are good points. There's also the fan factor. The more you go to DL, the more you buy other Disney related stuff in general, whether at the park or at other stores. It starts with simple things - a jacket, birthday card, stuffed animal for a special occasion. Suddenly you realize a little here a little there adds up. A scarf, a pair of socks, an art print, a shot glass, a dog bowl, a phone skin, a pot holder...

And then you get the collectors. Pins, of course, but there's figurines from Disneyana, cels from the Gallery (I do miss that place), huge coffee table books, original concept art, art by other artists inspired by the Mouse...

I think keeping people coming to DL has its advantages, and that even when I stop going it still leaves me wanting this stuff. Of course it's impossible to know exactly how the numbers shake out, but from my own experiences and the experiences of others around me, it's gotta be worth it.
