We just did the Disney After Hours event at MK last night 11/18/19.
It was honestly one of the best Disney investments you can make. I understand for a family of 4+ it can be a big pill to swallow, but you can get so much done it's ridiculous.
The only time I experienced crowds so low was the day before Hurricane Irma was inching towards Central Florida.
7DMT technically listed a "wait" of 20 minutes all night, but it was pretty much less than 5 minutes. They were making people walk the bulk of the queue not to overload the loading station.
Depending on what time frame DAH runs, you can get in as early as 7PM, and you can make FP+ for those hours prior to the Event.
Over the course of the event we did the following;
7DMT 5x
Pirates 4x
Haunted Mansion 3x
Jingle Cruise 3x
Peter Pan 2x
Buzz 2x
Teacups 2x
People Mover 2x
Tomorrowland Speedway
Aladdin's Magic Carpets
It's A Small World
Throw into this several bottle of soda and water. About 6 ice cream bars and a box of popcorn between me and my fiance.
For $200 it was the easiest and most relaxing touring of a Disney park I ever experienced.
