The hotel definitely has say in it. I can't remember if it was 2K5 or 2K4, but something we thought would be okay (it was metal, but not edged, I think... can't remember for sure) the hotel came back and said "not okay." Between that and the legal ramifications (and I'm unsure, but I think it may have insurance issues as well, which only compounds it), we can be pretty sure that live steel will never be allowed - which, IMO, is a good thing, since some people can be counted on to always be irresponsible and willfully ignorant of the rules.
It's the stupid ones that ruin it for the rest of us...
