Leaving aside Disney serving the quests thing (which given that over the past decade or so attendance has done nothing but increase, which would seem to be the only indicator you need that they are serving the guests) yes I am genuinely shocked and can not understand anyone who like or want to sleep in on vacation at WDW.
While I think for the most part I am getting value for what I am paying for at WDW, by no means do I think its cheap. Its expensive to take a family of 4 to WDW. Why in gods green earth am I spending all the money to go to WDW to....sleep in? I have a bed at home. If my idea of a vacation is to relax and sleep in, I can do it there and pay nothing. Or I can choose any number of other destinations that are cheaper than WDW, or that are geared more towards a restful relaxing vacation. To me it would be like the equivalent of spending a premium to stay at a luxurious beach resort....but then not wanting to go into the water. Its the same reason I don't get people who talk about "resort days" or who are so concerned about how the pool is. The pool????? Again I have a pool at home, or our town pool, or any other number of places that if I want to go swimming, I can go to that are cheaper than WDW.
But hey listen, to each their own. If you want to waste (in my opinion) your time and money sleeping in late while at WDW, that's your right. But don't complain when WDW gives people the option of utilizing a system, and gives everyone that option, and some people decide to wake up early to maximize the efficiency of the system, and you decide not to.
