No, when it happens they find you another hotel room in a nearby hotel and either drive you there or have you driven there on a cab. But is not at all common, and when it happens it is more likely that the reason is not overbooking, but rather some incident (like a mistake in the bookings, a bathroom found leaking just before the customer arrival, a couple that booked a twin and then arrived with a 17 year old "kid", etc.)
