Jen: I'm not convinced magical people need that much sleep to 
survive. Snape is constantly wandering the halls and Dumbledore is 
out a fair amount himself (when he's not up talking to the 
portraits). McGonagall seems to be on-call for Gryffindor 
emergencies, which happen frequently enough to suspect she's a light 
sleeper at best. Maybe Barty Jr. just woke himself up every hour to 
take his Polyjuice? Or he slept in the trunk with the real Moody! 
With his history, no one would think twice about him sleeping in a 
locked truck.
