Hi Betsy,
All of the dates you have listed are great times to visit Walt Disney World.
The weekend of Thanksgiving is very busy, so I would take the Nov 25-Dec 1 off the list.
I would want to go sooner than later so Nov 11-17 would be my first choice and the dates in Dec would be my next choice.
You will absolutely love Mickey's Very Merry Christmas Party. It is such a fun filled night, it is a must do over the holiday season!
If you can book
character dining, that would be another fun option. Your little one will love having a meal with their favourite character. That continues to be a favourite for my kids.
You will also have to stop in at the Grand Floridian resort and see the
giant gingerbread house--it is magnificent.
Check the long range forecast just before you leave so you have an idea on what kind of clothes to pack.
If you have any other questions, please let us know!
Carrie
