Well, then why don't you explain either where it is that you frequent or which hotel programs have what brands there?

Choice is another such program, though not all of their brands have suites, not all of their programs allow you to book suites, and the suites aren't always much (sometimes just a room divider), and this may work better in some places than others.

Also, obviously, any program will allow you do redeem points for suites at an all-suites property. Most programs have all-suites properties: Hilton has Embassy Suites and Homewood Suites, Club Carlson has Radisson Suites (a subset of the Radisson brand), Marriot has Marriott Suites (a subset of the Marriott brand) and Townplace Suites and Springhill Suites, Priority Club has Staybridge Suites and Candlewood Suites, Choice has Quality Suites (a subset of Quality Inn) and Comfort Suites, etc.

But again, without knowing where you want to stay or without knowing the list of chain hotels in that area, I can't tell whether that would help you or not!
