I personally wouldn't take a 2 year old to WDW. We've been 3 times -- twice with a 2 year old -- and with child 3, I'm definitely waiting til she's 4 to go again. I know I'm in the minority on this thinking, but I think they get the most enjoyment 4+. It's a big ordeal and expense to do the WDW experience, so I think it's best to go when they can get the most enjoyment.
