I was planning on staying out of the parks Sat of Mem weekend, but how crowded will DTD marketplace be on a Sat afternoon? Will the line for Earl of Sandwich be crazy?
It's always busy there on the weekend. It doesn't matter what time of year.
You're best bet would be to get there by 10:30AM. Especially if you want a good parking space.
That's what I have always found out anyway.
Hope this helps.
