When do they post the dates for these. I am trying to decide when we are going. orginally had planned on sept-oct but now am thinking of nov.-dec. and trying to decide which of these would be more fun. I need to know when the dates are for 2006 so we can figure out when to go.

There are FAR more characters out and about at MNSSHP, as I only saw a handful at MVMCP. ToonTown was dead in MVMCP, while at MNSSHP it was hopping with trick or treating stations. There is a "goal" at MNSSHP - to get candy! MVMCP, I guess you just experience stuff. I just felt that MVMCP did not have enough going on that made it different from a normal park day at night. MNSSHP made me really feel in the mood of Halloween, but MVMCP didn't get me into the mood of Christmas.
but I have no plans to MVMCP anytime soon.
