I had this happened to us once. Once I was travelling with two of my friends where we booked one room and listed the guest numbers as two instead of three to avoid the extra guest charge. Initially we thought they would provide us with two queen size bed which would sleep a total of four guest. But when we walked into the room, only two single beds were provided so one had to sleep somewhere else. Luckily I forgot to remove the sleeping bag out of my trunk the last time I went camping, so by the time we arrived at the hotel, the sleeping bag was still there for one of us to utilize during the overnight stay.
