It's all very well trying to sleep in a hotel room if you happen to be downroute. All you have to contend with there is cleaners banging around outside the door all day! It's far worse when you are at home.
When you're at home, people assume you're awake, so they phone you, drop in for a cuppa etc. Then there's the kids who suddenly find Daddy's home, "yippee, wake up daddy, let's play bouncing on your bed".
