Generally, the first week is light. However, I have a lot of guests going then (especially from Georgia), so I'd expect it to be moderate. Hopefully not too busy!
I'm wondering the same thing, as we will be stopping at MK on Jan 2, only for the second 1/2 of the day. So from like 2:00 until our DD is ready to go (or the place closes) Does this sounds like it's worth it?
We won't be paying for the entry as we already have passes to be used.
