As in any famous theme park, and add to that the peak Christmas travel season, there are a lot of people everywhere!!! But it does not matter... For major rides, take advantage of the FastPass. I found this very helpful. All staff are graceful and helpful, despite that they had to work extended hours and even if there are really lots of people visiting that day. Very organized and efficient during the parades. Note though that fireworks will no longer be shown after 1 Jan 2018, so lucky me that I made it before that.. to have a magical experience to witness the last few fireworks display.
