Like [MENTION=781355]phant0m[/MENTION] said, that's probably just how they name their rooms. Check the "rooms and suites" page on your hotel's website. I didn't request any specific room, I just said "I want to make a reservation using a Club Upgrade certificate from the Chase Ritz Carlton credit card" then after she looked up the property and dates I asked for the cheapest option and rate.

Also, I've heard it may be different at some properties but at the RC HK there doesn't appear to be any difference between a Deluxe room and a Club Deluxe room other than which floor they're located on. The description for both of them, including square footage and floor plan, are otherwise exactly identical.
