I read up some info on the Internet, and particularly, the ins. website. I don't think they can prohibit you from deciding to stay in a hotel, or with family, friends, etc., but they can decide that they are not going to pay for a hotel, etc., if the damage is not assessed to be dangerous.
Imagine if the co. said you can't leave your house. They would be in for some major lawsuits on so many fronts.
