I haven't been to MNSSHP, but I have been to the Christmas one on a sold out night. It was great, and just like the earlier post mentioned, the lines get shorter as the night goes on. The atmosphere was wonderful, and everyone was in the best mood. I would highly recommend the experience if the Halloween party is anything like it. We waited no more than 15 minutes for anything. It was really great. It would never substitute for a full day in the MK, but we did it on an extra evening that would have been free. Go go go.
