Osborne Lights tend to go on for the Wine&Dine Half Marathon (which is at night), then being open for the public the following evening. This year that run is November 7. Food&Wine Festival goes to November 16 this year (longer than normal, apparently). The last Halloween party, it seems, will be November 1. The first Christmas party is on November 8!
Jersey Week is when many people from NJ visit because of school breaks; it's normally the first week of November.
So from there you can figure out when the best time for you would be.
