Guests arriving late (in evening) at the hotel. Can they still check-in?

Normally there is a Cutoff time within the hotel which differs from hotel to hotel. In a Normal scenario guest can check-in in the evening as they have already paid for the room and it’s confirmed but this depends on the discretion of the hotel management. if guests are arriving late, please notify us of the arrival time in order to inform the hotels to hold the room and not release the room so that guest can check-in without any trouble.
