One of the challenges they have too is the "don't change the elevator" situation... Yes there are plenty of staircases, but in "theory" there is one elevator for the access of guests to the second level...
I'm not convinced that Garden Tea Room doesn't come back in some form... Maybe I am being optimistic, but particularly with the addition of the lobby bar, it would actually not be too hard to staff an afternoon tea on a limited basis and use the space for activities and private events.
I am curious what the old Sugar Loaf Concierge Lounge has in store and all the other vacant spaces (kids club, Summerhouse, etc.). To me, those are all revenue generating spaces that should be considered.
