Haven't done one at WDW yet (though we did get tix for the 5/13 at Epcot) but have done the one at DCA last year. Lines were long! The shortest wait was for ice cream bars. Now, mind you, I have heard the DCA event was poorly planned and executed (which I have to agree) since it was the first event of this type for DCA. I hope Epcot's is smoother, and I think it should be since Epcot has more to do and more space.
