All major holidays are crowded at WDW, and this was no exception. We knew from researching typical crowds on this day (and from experience during other busy days!) that it was very likely that the Magic Kingdom would close to guests at some point. Because that is the park we wanted to visit, we decided to make breakfast reservations at the Crystal Palace in order to get a jump on entering the park.
All in all, it was a great way to spend the holiday, and I would do it again in a heartbeat!
