It was a group of 7 travelers, one still unaccounted for, some had room on 7th floor, some on 5th floor, however the 6 and their luggage were found gathered in one garden villa on the 5th floor; 4 in the living room, 2 in a bedroom; all were supposed to check out on Monday.

What is puzzling is they were found on Tuesday; when I check out even one hour late I have the reception on the telephone already, let alone a full day.
