At check in you will get the gift card(s) emailed to you. It's not an actual card, you can get a print out of it or you can add it to your Apple Wallet. It is not linked to a MB and you cannot charge meals back to your room and pay with it at check out. There will be a barcode scanned at the dining location you are at for payment. If your credit is more than $1000, you will have 2 gift cards. When I go, I will have $1500, so one card for $1000 and one for $500.
