mucknet, Hilton HHonors is a loyalty program for the Hilton brands similar to a frequent flyer program for an airline. The site you checked out is simply for the card, a marketing offshoot of the program.

www.HHonors.com is the website you want to for all the details of the program, including how to redeem for all the good stuff (not for airline miles). So now you get to spend a few hours perusing another website.

Be sure to check out the links I posted above, too. They contain some of the answers your looking for. And the Hilton forum is very valuable, too.
