If you do go, plan on going against peak times. All the families, with little kids? usually they plan to be there when the park opens, and thne, by 3p,m, the kids melt down, lose it, and mom and dad lose it, too!
Afternoons are good.
Or, Friday after Thanksgiving at Disneyworld. NEVER hit Saturday after thanksgiving at EPCOT. Disney gives free passes to residents of the county for that day.
Thanksgiving weekend is actually one of the slower Disney weekends. So, go then.
You're right on that. Mid afternoon the whole well-planned vacation falls apart for everyone.
There's a whole community of insiders and fancy websites that give you the prime (and worst) times to hit Disney.
