I didn't go to Rainfurrest this year, so I don't have any firsthand experience, just reports from friends:
The fire alarms would go off for no obvious reason, and multiple times (because the hotel doesn't know how to reset the fire alarms, from what I heard)
"Adventurecru", a stinky bucket of shithead trustfund kids from Pittsburgh, gave a panel on con horror stories. (I'm not sure they included the part where they only know how to make airhorn noises during dances, because, again: not there)
A noticeable contingent of grown men in pink clothes and overalls, carrying pacifiers, were spread throughout the con, and I heard another thing about a room having to be cleared out because of the foul odor.
Con staff seemed stressed, mostly about money.
Any further reports?
