One think I just thought of.... Hyatt should know exactly where these stolen certificates were used as well as the name of the guest, if they were checked in. They could easily reverse the gift card balances and charge the card on file for the value that was used on the certificate.
If they're called on it, they could say it was a stolen card and to contact the person who gave it to them.
