I did this last year. I hear on dizpins that there is one scheduled for this year also. Not sure if I'll do it again though. At $99.99 a person, not really sure if it was worth it to ME (JMHO). You got to go to MK after closing and there was entainment and a dinner buffet. Several rides near the HM were open, (BTM, SM, the boat, country bears). This is considered a merchandise event. You preorder items (jackets, shirts, figurines, PINS which are limited) and are selected to buy them by a random selection system. It was neat going to the first ever at WDW, but I'm a little burned out by the merchandise events myself and look forward to my next visit to WDW to just relax and enjoy and not stand in too many lines to buy LE pins.
