This tip isn’t just about Walt Disney World, it’s for traveling in general. Always have at least two ways that you can pay for something. Carry some cash for an emergency, and it isn’t a bad idea to have a second card that you can use. Once when I was at the airport, flying home from Disneyland, I tried to pay for our meal and my card was declined. Fortunately, I still had cash. My account had been hacked and the credit card company realized that there were fraudulent charges, so they froze the card. I got it worked out when I got home, but if it had happened earlier in the trip I could have been in trouble.
