Why aren't the parks open late in late March?

[disneypolybride2008]

Hi. We're going during Spring Break time, peak time too. Only one day of our stay the MK is open real late. Other than that day all the parks are closed by 9pm or 10pm at the latest. Why? Isn't Spring Break time popular enough to make the parks stay open later?>:confused3 :confused3

the park hours from last year show that the MK was open 12am-1am w/ magic hours the whole last half of the month.

You might say that you have what Disney would not consider a popular spring break schedule. The most popular weeks for Spring Break by far are the week before and the week after Easter; that is when you will see extended hours, because that is when the REAL crowds will be there.
