I have been in 2007, 2008, 2014, 2015, 2017, 2018 all in Labor Day week for 10 days, we did 7 this year, and I can promise you, it was 2007, 2008.. level slow. I know what I am comparing to, we are very familiar with this time of year. It was flat out, amazing slow. May not continue, but it was solid slow, except for the last weekend, and only crowded at MK and Epcot. Weekend only (Food & Wine) Wait Times were exaggerated. Take that with a grain of salt, but it was slower than it has been in a long time.
Edit to add, going back for a short trip to see the lights, in late November, a 9 day trip in early May. To beat Star Wars crowds. Nothing, and I repeat, nothing will make me go when Star Wars Land opens. I will take a break to let it die down. I really don’t think I am the only person, that will do that.
