And, of course, all rooms are booked solid, and you're kicked out to seek another place to stay. There are ways to prevent this panic situation from happening. Just think and communicate ahead.

Call the hotel several days before your expected arrival and confirm the reservation number and dates you’ll require a room. Ask and write down the name of the hotel clerk who confirms you. After you have all the info and numbers, make a hard copy printout and have it with you at check-in.
