Just received our passes from Undercover Tourist in the mail today. Our trip is not until November, but I am anxious to link them on MDE account. Is there any advantage to waiting or does it not matter? Also, will we need to take the actual passes to the park with us on the first visit or will we just use our magic bands. (I am sure I will take them anyway). Our past reservations have always been package deals with Disney which included our passes, so this is a first for us.
