I'm not going to bother posting a poll but I suspect most people consider anything under a mile to be "walkable", maybe less if the person is going to be carrying stuff. I'll speculate the site that suggested outlets are walking distance of DTD meant the Crossings shopping center.
I would certainly say WDW isn't drivable from Michigan, in one day.

I'm sure there is some distance at which it no longer really "walkable." But I'd hate to think that distance is something that can be walked well under an hour. Believe it or not, tons of people get up early every day at Disney because they want to walk that far - they actually enjoy it. 2.5 miles is not some unreasonable barrier. Sure, lots of people don't want to walk that far, just as I would never want to take a multi-day cross country drive. But I'd never tell somebody that WDW isn't "driveable" from Michigan. Would you?
As you suggest, probably best just to tell somebody how far the walk is and let them decide if that is or isn't walkable.
I'm going to assume the original poster isn't an idiot, and understands that you sometimes end up with a lot of stuff when you go shopping. I think it safe to assume we don't have to point that out. The OP specifically asked about walking to the outlet center. I think it better to assume either (1) they are thinking of walking there and taking other transportation back or (2) they are looking to buy something small.
