I've seen some pretty flashy lobbies and interior spaces in Boston (Brigham and Women's) and Providence (Lifespan) where you get the hotel impression. I could not find easy-to-point-at pictures, but there are some littered around (best I can show is http://www.discoverbrigham.org/2017-discover-brigham-photos-... which looks like a convention hall but is actually shot at the hospital). As soon as you get past them though to the functional spaces it usually turns into the traditional easy to clean hallway systems, but some of the lobbies have that marble, high ceiling, hotel lobby kind of look. There are plenty that I have been to that haven't exuded that kind of feeling however (or were an alternate entrance).
