How much of this do you think is a result of WDW price inflation tho? In the last 25 years, WDW went from a family vacation on the high side of average to the cost of a new car for a week. When the meter is ticking at $10 a waking minute, I think it encourages the commando style (and skipping the small things for the headliner attractions).
It's a factor of course - people wanting to get their money's worth. But part of that is because of the way Disney structures their tickets... trying to encourage a continuous stay and such heavy front-loaded prices.
But how does the guest compute value? That's the portion that has been distorted and manipulated. Disney has driven the 'gotta see it all' mentality as a way of trying to encourage longer stays. But the consequence is people can't stay longer and longer, so instead they try to rush more into a set time. The picture Disney has painted as what the resort is, and what the 'ideal vacation' includes influences people in ways that most people are oblivious to. With repetition and exposure from all sides, people just take for granted this is 'right' and how things are supposed to be.
Just think of how many times you've heard a conversation like this:
Joe: "how was your trip? was wdw fun?"
Jill: "sure it was great, but we didn't get to see it all..."
The letdown or disappointment in not doing ENOUGH. That's the kind of 'gotta get them all' behavior Disney has been encouraging and people are soaking up without even realizing it.
Now.. people can't possibly risk 'wasting' a day doing something like canoeing or sitting by a campfire... we can't waste that time when we have rides we haven't seen yet in the park!#!#
People forget just how different visiting patterns while at WDW have become vs other vacation destinations.. or even WDW of the 1 and 2 park era. And it's not all good.
