How it works: the traveler books a hotel room in Hanoi
, even in a place with great reviews, and then gets refused to be accommodated in it due to ''technical issues'' and is proposed another room. Set up: the hotel oversells the most expensive rooms on purpose to earn better money. Then, when the client arrives, the hotel stuff explains that the room booked has got technical problems. However, they refuse to show the supposedly damaged room. If the client does not oppose, he/she gets transferred to a cheaper room or hotel without repayment. Places to beware: Hanoi and other Vietnamese cities. What to do: if refused to be shown the room, insist on it until they give up and provide you with what you have booked.
