It is my favorite time to visit - MVMCP is not to be missed - if you don’t have young kids then take in the later parade it’s less crowded. Also remember the fireworks at the party are different then the fireworks on regular nights normally (They do show the same fireworks on regular nights when it gets closer to Christmas)
Don’t forget free cookies and hot chocolate also.
I also highly recommend the Candlelight Processional at Epcot, if that is of interest to you

Lastly you must visit the Osborne Family Spectacle of Lights at DHS

Hope this helps - I’m trying the Halloween Party for the 1st time this year, so I know what it is like not to know what to expect.
