That remark about "their room" sounds like production taking over a banquet room at the hotel. A place where they can do confessionals and sequester the teams. Production has done this before. I can remember one in Guilin, China in TAR15 and at Heathrow Airport in London in TAR 15. In China, they released teams in the same time frame that they arrived, but then teams hit a HoO at that drum deal on the mountain.
