As surmised, The Golden Room is on Royal's Asia-based ships and is a "high roller" casino, invite-only. I've seen it on Spectrum and Ovation, and it has only a handful of Baccarat tables and spaces for private bar and buffet. It must be easily-convertible, because i again saw it on Ovation in Alaska when the space was converted - IIRC is was part of an expanded Diamond Lounge, and the only obvious difference when in the US is that the Golden Room signage was gone but it still had a TON of ceiling cameras- every few feet. I can only imaging the money that goes through there into Royal's coffers when in Asia.
