A few things on this.....
1st, I'm not a fan of the room charge thing. Using the Magic Bands MAY help cut down fraud, or it may not. Only charges to the bands in your room should show up....but......we all know about Disney IT.
2nd. This is why I do NOT use Debit cards. If you are defrauded with a debit card....this is actual cash money that comes directly from your bank account. Getting it back is EXTREMELY difficult if the bank doesn't catch it first.
3rd. When using your CREDIT card....you are responsible only for charges you make. You can dispute any charge with the bank....but none of your money has been taken. If you dispute a charge....don't pay it. You technically have not had anything taken from you. The bank has. There is enough video surveillance around disney to investigate all purchases if the credit card wanted to pursue it. It's call credit card fraud because it's your credit that is used....not your actual money. It's always on the bank to investigate fraud, not you.
Southern California is the Credit card fraud capital of the world. At DLR they check Photo ID with EVERY credit card purchase. Whey they don't do this in Florida is beyond me.
Personally I only use credit cards because I hate debit....but also for the Reward points. They pay my
DVC bill
