Saw these two in the Park the other day and quietly thought that this would have made a great "WAI"... "Where Am I?"... ; Apparently in the wrong park!
My wife and I saw them too and did a double take as we were walking away from TOT. The best thing is that they were even carrying their wands.
Less of a "WAI" and more of a "WTH?!" Why on Earth would two people be wearing Hogwarts robes in a Disney park? The only thing I can think of is maybe they had just come from seeing Deathly Hallows at DTD.
