We had to sleep on the corridor one night because there was no one waiting for us, and there was no way of contacting them, even though we had advised them for late check-in (flight was supposed to land at 22:15 but it was delayed and landed at mid night). When we arrived at the hotel at 1:36am, there was a sign saying that the check in was until 1:00am, so if you arrive after that, they don't care, you are alone my friend. It did happen before, it will happen again...
