Ugh, I am so glad my roommates for cons haven't fooled around in the hotel room... that I'm aware of. Better off not knowing.
Normally if I'm in the room, I'm sleeping, eating, changing out of cosplay or helping others with their cosplay. At night after I've retreated to the room, its usually shower, maybe listen to music I'm waiting on others for some reason and then fall asleep. I've tried playing games on my laptop but I haven't had too many hotels with free Wiifii in the room and the particular game I wanted to play required Steam.
