My daughter also received from Aeroplan (so exchanged for points) an 8 x 10 sheet of paper which is supposed to be her 3 day park to park ticket (there is a bar code on it). It really is rather big to carry around, versus a card and yes, I imagine she will have to show it every time she enters a park or rides the Hogwarts Express. Maybe we'll be able to exchange for something smaller at guest relations!
