We just used this Disney Visa perk last week. We had Minnie and Goofy. Be sure that they give you a "coupon" when they check you in before the photo session. I got nothing to "prove" to the camera center that my pic was from the Disney Visa meet and greet and it was a big ordeal. They insisted that they should have given me something and I insisted (nicely) that they did not. In the end they called the meet and greet workers and got it verified. Long story short, get the form, coupon, whatever it is (I still don't know-like I said, I didn't get it!). Have fun, it's a nice perk!
