I booked a hotel. 18:00, and I need to pay a deposit when I arrive at the hotel. My car will definitely arrive after 18:00. Will the deposit be refunded after I check in?

Guaranteed reservation is a protective measure taken by merchants for fear of losing the bill, because after 18, the hotel will enter the peak period of opening. After you guarantee the reservation, whether you check in or not, the reserved room will be reserved for you all night. If you don't check in, you still have to charge. If you check in, you don't have to pay the room fee, but you need to pay a deposit! You can also pay directly at the front desk, and then the agent you booked will refund the deposit!
