Yes, Suite 44000 in the Oregon Building was "Bugsy's Suite". Did the door you saw have an engraved gold plate on it that read, "Bugsy's Suite, 44000"? the plate was on the original door, but someone like myself may have gotten off with the plate!
Passageways, yes. Bullet holes, no. Was able to pick up several pieces of stuff as we were in the hotel the week that started tearing down the old buildings. Actually have a piece of the Oregon building that I managed to get and it is displayed in my den! Some places have a piece of the Berlin Wall, me, I have a piece of Bugsy's Building!!
