I believe you're still on duty. In other words they pay you per day whether you're flying or sitting in a hotel. I wouldn't think you would be required to sleep in your uniform waiting for a call to your room. They usually know the schedule for the next days flying, but you are subject to change. About all they can say is "report ASAP". He has been called at home with the 1st days schedule at say 18:00, only to be called back at 20:00 and have it changed. They usually stay at Crowne Plazas, Double Trees, Hiltons or equal, depending on what is available. Downer is that it's usually near the airport, not necessarily downtown. They give you a company cell phone, so they can get in touch with you just about anywhere. Some places where they lay over, the FBO will even give them a crew car. All this and a LEATHER JACKET thrown in. WOW !
