Maurice,
Thanks for your question! What day to go to the Magic Kingdom is often determined by what special activities are going on. Often if they have a special morning access event, like Early Morning Magic, it can be a reason to go somewhere else to avoid slightly elevated crowds. It is also good to know when special events, like the
Epcot International Flower & Garden Festival that is going on when you are there, might cause larger crowds in a park. In your case, that festival makes the weekends a bit more crowded.
For the time that you are coming, here is where I would suggest you go, by day;
You may want to tweak this schedule, based on
Extra Magic Hours, and if they appeal to your group. When my kids were young, we knew we could not take advantage of evening ones, so we avoided the parks that had those, so as to avoid slightly elevated crowds in that respective park. As you are going there at one of the less crowded times of the year, however, you may want to take advantage of either the morning or evening Extra Magic Hours, dependent upon your group.
Write me back with more group information and I am glad to offer up more planning advice!
Have a Magical Vacation!
