I definitely agree evenings are better. Holiday crowds = more families with small children who are up early, in early, then out early. We had a flight in the evening so couldn't take advantage of evening MK crowds.
Not that you're doing this, but I see it all over the boards: can we normalize people who were in the parks each having their own experiences? We've been almost 20 times and in MK probably closer to 40. We know busy, and not busy. We overheard plenty of unhappy people during our time in lines yesterday. We know when it feels like WDW is cutting corners by not staffing appropriately vs. the before times (before park reservations) when they could be caught off guard. We had an awful time yesterday, and not saying that's all Disney's fault but get that's not the case - nor would I want to be the case - for everyone.
