I'm on the fence about going. We're a group of 10, so $700 to go for an evening. 4 or 5 hours. Compare that to just staying at the Poly for a whole extra day for that much. It would be neat to do, and I've got a day it fits nicely in after an Ohana dinner. I just don't know. People are so split on it. Even on this thread, for each person saying they love it there is another saying it's not worth it. Some say short lines, others say long lines. Some say to expect shorter lines close to later at night, and I found lines stay long pretty late, so I'm guessing those who say they find short waits might be off a bit, or at best it's varied.
Even if we could get on w short waits. In 4 hours ride a bunch of rides? We could do that during a day, I think the point of going to the holiday party is to enjoy the holiday stuff, not just ride the rides that you can do any time. (thus, the shorter lines). I would do it if we could meet Sandy Claws w a short wait, but if it's a 3-hour line to do this then we wouldn't. Other characters are not really important. We'd want to see the parade, fireworks, and parties.
On the other hand, this will be probably the only time we go around Christmas, so it's kind of if we don't do it this trip, we probably won't ever.
Would we be missing out? We have 8 days of parks. 3MK, 2EC, 1AK, 1HS, 1DQ. So it's not like we're hurting for MK time. One is a regular day late night even, so we'd be able to see the MK at night. Other 2 MK days are
MVMCP days, so it's out of there by 4, unless we want to come back for the party.
