Not until they start to deal with the hotel owners for their secret agendas being leashed on customers, I've heard of similar case related before whereby the hotel hid some mini cameras on the AC panel, fan, table lamp, water heater and the bathing tub, these are ateas tgat are sensitive for caption and all dealings that comes with privacy could be achieved in such strategic location, they can even caption the bedroom and bathroom nude of a customer without being aware, and theu uses such against them later in future, which is total violation of human right, those specific locations should be investigated and thoroughly checked well lodging in a hotel.
