I’d go the first week of November. The weather should be awesome. It’s still hurricane season, but those are far less likely to hit then than in late August/early September.
That week won’t have too many parties, which really mess with your week at WDW IMO. The F&W Festival is still happening, and depending on how the week falls, you may get to see both Halloween and Christmas decor.
It’s the best of all worlds. Don’t let tales of “Jersey Week” scare you. There are not enough NJ folks who can afford the air fare to impact park crowds noticeably.
