Today is our last day here and we cashed in $1550 in Disney Visa Rewards points for this trip. I have used it for our dining, and after last night's dinner, I only have around $26 left on it. When I use it tonight at Be Our Guest, I will have to pay the balance out of pocket after using the remaining points. My question is, do they have to know the exact amount left on the card to be able to use the remaining points? I must have thrown away my supper receipt last night and I don't remember the exact amount left on the card. I work at Walmart and from my time cashiering, there are some cards where you can swipe the card and the system will automatically use the remaining balance even if you don't know the exact amount on the card. And there are other cards where we have to type in the exact amount left on the card if the balance of the purchase is greater than the balance left on the card.
