18 is the minimum age to book a hotel room. You'll need a major credit card and form of ID. It's only 21 if the room you were staying in had a mini bar. The Sleep Inn rooms do not have mini bars. The rooms are equipped with a refrigerator, microwave and single serving coffee maker.
Do you mean FB check in? Or do you mean book a room? If the latter, I believe 18 with a major credit card. Could be 21. I'd call the hotel and ask.
