Money buys you things. It's the capitalist way.
But why would anyone stand in such long lines to begin with?
Kids cry. Parents are stubborn. The excitement of the moment. The once a year or longer opportunity. The price of parking. The ubber disgust of having to return and try the line a second time. The good rides always have lines. To aggravate your parents. To aggravate your kids. To do something while drying off from the water ride. To hide. To blend. To try a different seat. To find your hat. You promised your cousin a first hand experience report. You have one barf bag left and you need to use it before you fly home.
After living up the street from Disney for 17 years, I can supply you with more answers, but you get the gist. :-)
