I'm not sure but I think the December 16 will still not have the xmas parade and I'm not sure about Country Bears... you'll have to research and maybe post this question as a new thread but I think the X-mas parade is only the last few days leading up to Christmas Day.
Not going to
MVMCP, you'd probably miss:
The snow on Main Street
The free photo and pin
The free hot chocolate and cookies
The 2 parades
The amazing fireworks with Rudolph flying down...
Supposed limited ticket sales so supposed low crowds for rides...
