you buy an admission bracelet[$12.00per person] that, on certain nights ,allows you to stay after MK park closing to enjoy 10 rides.space,splash,big thunder mountains,extraterestial Alien encounter,buzz lightyear,astro obitors,haunted masion[sorry thats all I can remember].
And it is the most fun!!
TO be in the park after Dark with only a few people!! and To have no lines!!!!!!!
