Well, first, Pop Century isn't always the furthest bus stop (at DHS, it's pretty close to the park entrance); but aside from that, moving walkways wouldn't work because you'd have to have SO many points of entry/exit, plus with multiple entries you'd have people cutting each other off...
I guess I'm not seeing how this relates to Guest Comfort

: Guest wallets, sure - but believe it or not, not everyone brings computers on vacation, and so not everyone should be expected to subsidize the cost of wireless connection for those who choose to be/stay connected.
But SO much of Animal Kingdom IS the animals. It just makes sense to close the park at a reasonable time as far as the animals are concerned.
More buses = higher costs.
But that's the whole point of FastPass - to avoid waiting in line for two hours. Now, granted, Disney's original expectation was that Guests would spend money - shop, eat - instead of visiting other attractions; but FastPass allows the Guest to get food, go to the bathroom, visit other attractions... while waiting for the FP time, AND it avoids clogging up the waiting area.
I wasn't going to address individual "give us free wi-fi" posts, but... sure, HoJo's does. Many properties in the same category do. Higher-end hotels, and resorts like Walt Disney World, don't because, well, the competition doesn't. It's all about the competition.
Again, WDW is a resort, not a "cheap" hotel - and again, it's all about the competition. There's no reason for Disney to include Continental breakfast when its competitors don't. As for changes to the Dining Plan, well, Disney already offers three versions. Four, if you include "don't get any Dining Plan, pay out of pocket, eat exactly what and how you want". Remember, the Dining Plans are options, not mandatory.
Wouldn't work. You'd have to have (a) a cut-off time by which the purchase had to be made; (b) some system to collect purchases about every ten minutes; (c) some system to deliver to each resort every ten minutes; (d) a mandatory "you can't leave before ___" policy for the Guests; (e) a LOT more Cast Members - for collection, sorting, transporting, delivering the merchandise.
Sort of belies the definition and purpose of "in the Disney vault" though, doesn't it?
But Disney doesn't want you in the room relaxing (sleeping, okay, but not 'just' relaxing). They want you out of the room spending money!
