And then there's how many floors any given hotel might have, as well as where the convention activities take place. The hotel I work for has four, the hotel AnimeIowa has been at for twelve of the past fifteen years has eight, and the two times I went to ACen, their hotel had fourteen floors. I'm given to understand that the hotel that hosts WisCon has between twelve and fourteen floors, and most of the action takes place on the second and sixth floors.

I'd have to prioritize whether I want to do something different for every floor (definitely better for getting people to use the stairs, but potentially harder to organize), or to target the stairs that people use the most often. Especially for taller buildings, I wouldn't want to do the same thing for every floor, because then people would only have to go up or down one flight of stairs to see the cool stuff, and then might switch right back over to the elevator. On the other hand, if I did something different for every floor in a hotel that has fifteen floors, some people might take the stairs in one direction just to see everything, then take the elevator back to whichever floor they actually wanted to go to! Making sure that people can see the exhibited art right after it gets taken down would do a lot to eliminate that problem.
