Well, if the idea is that the people are all stuck in the house, one real-life week of peace seems like enough in between the big action. But maybe that also depends on how exhausting the nights are for the players. If things are moving in real-time, does that mean backtagging wouldn't really work for the game and all threads would need to stop when it was time to switch from day to night or vice versa?
