Hi Jordan,
Going in early November will be a great time to visit Walt Disney World. While you will still get to enjoy the sights and sounds and special events of the holidays, you will also most likely avoid the busier times of the holidays including Thanksgiving week and much of the last couple of weeks of December.
Since they don't usually announce the dates for
Mickey's Very Merry Christmas Party until mid to late summer. Historically, these parties are held most always on Friday nights (with the exception of Thanksgiving week) and Sunday nights with other days of the week as other options. Typically, there is never a party on Saturday nights. Again, this is based on past years and is not guaranteed.
I would just keep an eye out on the
special events/tours page of the Walt Disney World website during the summer of 2014 as well as checking the
Disney Parks Blog as they will both be among the first to announce the 2014 dates.
Happy Planning and I hope it all works out in your favor to enjoy this magical event.
