To each their own.
I, for one, applaud the back-pack toting, stroller-pushing, souvenir-laden, tempest-tossed huddled masses yearning to breathe free. It is their slowness of speed that allows my family to breeze past, with all our worldly goods occupying a small crossbody purse and a few cargo shorts pockets, and beat them to the head of every line.
On a more serious note, I don't judge anyone who is trying to save money. I do not buy the logic that, simply because a Disney vacation costs a lot, anyone who attempts to save a few dollars here and there is being "penny wise and pound foolish." My parents took me to WDW several times as a child -- always on a shoestring, drive-down-in-an-old-van-and-sleep-in-a-leaky-popup-camper budget where every penny counted. We brought all of our own food and never spent a dime on food or drinks in the parks, and we saved hundreds of dollars on every trip because of it. We needed those savings, because even though my parents were a pair of hard-working teachers, paying for park tickets and a campground site were all we could afford in those days. We still had an unbelievably awesome vacation every time -- even if my mother's bulging purse was full of bologna sandwiches, warm cans of TAB and sweet upstate New York apples, instead of cash for souvenirs.
