I understand that a separate ticketed event called "Magic Kingdom After Hours" will be offered in early 2018 (was also offered in 2017). You pay a separate ticket admission price ($120), and are admitted to the Magic Kingdom for 3 hours after the park closes to regular guests (plus the last normal operating hour of the park).
My question is: Is anyone aware of how the Magic Kingdom After Hours event impacts the MK park crowd levels that day? Is the park noticeably more crowded overall, and/or during the last normal operating hour? Are the fireworks more crowded due to the After Hours event? Does the addition of the After Hours event make it less desirable to visit the MK that day if you are NOT attending the After Hours event? In an upcoming trip, I was planning a MK day on 1/30/2018. If I don't attend the After Hours event, I was wondering if I should avoid the MK that day. Thanks for any help on this one!
