That would be kind of you, thanks. Aside from the basic "Oh noes! Narrow escalator and people with capes! Someone will be strangled!!" issue -- which I presume the hotel just has lots and lots of insurance for -- the one thing that completely scared me away from Arisia was people wearing leashes (held by a different person) in public.

That was a total dealbreaker for me: they were involving me in something I couldn't bear, and I felt I had no right to ask them to stop.
