I too have an app in my iPhone to store my confirm #'s, so not really a big deal.... that being said i do see how this can be an inconvinience for some people.

My idea would be for Disney to add your reservations to you KTW card, so they could just swipe your card to confirm your time. (This would also create another perk for guests who stay on property as they would not need to carry all of their info around)
