I should add that some hotels do struggle more than others. I just checked out of the Fairmont Grand Hotel Geneva yesterday. They managed to redeem the card, but she had to check her notebook on how to do it, and had to go find the terminal and plug it in. Clearly, they don't see a lot of gift card requests there! Fortunately, the stay was only 1 night after flying in and driving out the next morning, so I only needed to redeem a single certificate.
