We did MK Thanksgiving week in 2013 when it was open till 3 am. DD 10 wanted to try and make it all night, and we stayed till about 2:30. We hopped from AK in early afternoon, and did FP for Enchanted Tales, Mermaid ride(was new at the time), and HM(DD's first time making it all the way through!) We grabbed QS at Pecos Bills and saw projection show, Wishes, and the late MSEP. By around 11:30- 12:00, everything was a walk-on or 5-10min. wait. We did Splash, Buzz, PP, Pooh, Monsters Inc., Haunted Mansion, and a few more I am not remembering I'm sure!(this was pre-SDMT). It was one of the best times we've ever had in the park, reminded me of some of the pics people were posting from the recent paid nighttime event. We had planned for a late nt., so had a late brft ADR at Cape May the next morning, and got a cab from CSR, so we could wake up later. Later that week, we met up with friends from home, and the kids wanted to go on rides together, so got to MK after late dinner ADRs around 10:00, got their DD on HM for the first time with about a 15 min. wait, did Tink meet around 11:00 with about 20 min. wait, then off to BTMRR around 11:30 with about 25 min. wait, then Buzz with 15 min.wait, then Monsters Inc. about 10 min., and headed out around 1:00. So I think it is definitely worth it to try, but it is a toss up depending on the crowds that day, and which rides you want to do.
Early EMH is still the best if you can get up early, as you know you are the only people in the park, and even for the next hour or two, crowds are still lighter. But having teens now, late EMH may be more our thing, as they do not like to get up early, and last trip in Dec. with just DD12 and I, I was trying to drag her up each morning, and missing RD, defeating my FP/not FP since we will do first thing plans!
