When you do online check in can you pick a pin for your credit card? Our credit card has changed since our last stay. I have it saved on the disney site. That is how I made payments on the trip.
Yes, in theory. But good luck - online check-in hasn't been working for me for at least the last 3 weeks. Same for a friend of mine who left last week. Let me know if you can get through the whole online check-in process without an error message!
