Are you sure they were charging the credit card or was it just using the card as the "key"? I saw a post on a FB group where someone mentioned that they heard Disney was now requiring a credit card for using the safe. People who are there now said that the credit card swipe was used to open the safe but no charge for doing that -- just a different method of unlocking the safe rather than entering a PIN. Did you see a sign that indicated there would be charges? Someone also said that their non-Disney hotel in the DS area used that same method -- swiping a credit card rather than entering a PIN to open the safe. It also seemed like most of the rooms at AoA still had the traditional PIN but a few had the credit card. Maybe they're testing it out or maybe just slowly converting. I'd much rather have a PIN than needing to pull out my credit card every time I want to open our safe.
