I went to dragon con one year, people were dressed in all sorts of costumes even though it's not a furry con. And I know the hotels where the con is are incredibly hard to book. That said just once I want some senior executive to accidently book a room in one because he has some meeting with a potential client of something and just so happen to click it at the right time.
He shows up and is completely bewildered by all the people in costumes. "you'll never believe it mark. I rode down the elevator with a robot and I swear to God... Tiny from Bob's burgers"
