Do HH numbers expire? A simple Yes/No answer would suffice - not a link to a "FAQ" page that itself is contains links to threads that are many pages in length.

The last time I stayed at any hotel was 1.5 years ago. The next time I'm likely to stay at a hotel is in a year+ from now.

I have an upcoming stay at a Hampton for 2 nights. Do I get at least a free bottled water or apple or candy bar if I check in with a working HH number attached to the reservation at the time of check-in?
