I was just scrolling through the HIlton forum and found this thread which may be of interest to folks here -- yikes! Hilton gift cards do not work at some Hiltons I've collected a handful of gift cards to date using my Surpass quarterly credit, but have not tried to use any of them yet. Similar to the Dell credit, it seems that some people are able to use their gift cards without issue, but others have experienced a range of problems. Sigh.
