I went to complete online check in for my October trip tonight. When I got to the page where you set the PINs for charging, it said that my PIN was already set. The problem is, I didn't set it! I could enter a PIN for the other adults in my party, but not me. The only thing I can think of is that I was at WDW in June (different resort) and had a PIN set for that trip. Do they automatically carry that PIN over for future trips? Thanks for any help you can give!
