Just completed a one-night stay. First time at this property. Drove into self-park on Harmon and checked in at Gold/Diamond line at Ruby check-in (wasn't my intention).
Was also upgraded from base room (460 sqft) to Ruby tower (700 sqft) as Diamond. The $15/$30 F&B credit valid for Kitchen Commons, in-room service, juice bar, coffee shop, and some of the bars. Not valid at other restaurants such as Nobu, Olives etc.
Bathroom separated from rest of the room via glass doors so if you have kids there is a curtain divider.
