What age to take to Disney World?

What do you think is the best age to take your kid(S) to Disney World?

My daughter is 5, we're taking her to DLand this summer. She's old enough to enjoy herself and remember it.

And not be a punk about walking.

4 or 5 we took dd at age 3 and she barley could go on anything

I say around 5..I remember begging my parents to take me when I was that age (they wouldn't because I have younger siblings, but I understand now lol) but we finally went when I was 10 and it sucked

IMO, never. Lol

I've heard 6-8 is the best time.
