My friend is going to WDW in January and has three passes with one day each left on them. One was her father's, one was her mother's and one was her cousin's. My sisters and I are going in two weeks and were thinking about buying her a new 4 day hopper in exchange for these three tickets. We are going to Universal, but wanted to spend one day at WDW. This is the opportunity for us to each have a one day hopper! Will WDW ask for ID for these hopper passes? Will we be able to use them? We are so hoping that it will work out!
