Definitely nice to have. ^ Although you've probably jinxed us into an announcement of award category changes.

Although I have to add that, of the major hotel chains, Hyatt probably has the best website (how rare can we say that for Hyatt and IT!) for finding properties and award categories.

There's no chance of finding a decent list with IHG or HHonors. IMO SPG and Marriott are also less user-friendly than Hyatt.
