We will be at MK on December 8th. We won't arrive until late afternoon with plans to hit a few rides but mainly to see HEA and fireworks. How early should I plan to get a great spot. Can i save a spot for my two adult children also? If so, what time should they plan to rejoin me? We'll have several other MK days during our trip but they're all party days. If they need to wait with me, that's fine too.
