Wow, we were at Walt Disney World in May of this year and we were unfortunate to endure the record rains! We were also rained out of some of our activities so I completely understand why you are wanting to try again!
All of the parades and fireworks shows are fabulous. I might consider doing one park a day since you have the 4 day base tickets. Plan to go early, do some attractions, head back to resort if you need some down time, and then head back to that park for any evening activities and entertainment. That way you will get a good taste of each park!
To check on the park hours and also the parade and firework and other entertainment schedules please click
HERE. You can view each park for the month of November to see the hours as well as the Extra Magic Hours being offered. To see the entertainment please click on each day you will be visiting and that information will show up.
You can also get a nice filtered list of attractions that are appropriate for your age children by clicking
HERE. You will see RECOMMENDED AGES on the left side and when you click on that you can fill in the information and a nice listing for each park will show.
To save time so you are not constantly trying to get from one place to the next for dining try to coordinate that with the park you will visit. Since you have advanced dining reservations for Ohana that would be an easy day for the Magic Kingdom park since you can take the monorail to reach the Polynesian and back again.
Anything you do will be magical and the important thing is to not try to do it all! That will add stress and enjoying a few things is better then racing around and not enjoying many!
