When I first arrived, the room I was given did not match the one I chose in the app, after I complained, the hotel informed me that the data entered was in accordance with what I chose, but I still insisted on choosing a room with a mountain view, not a garden view. When I wanted to upgrade my room, I had to pay an additional fee. I agreed to the additional fee stated. After I gave the wrong room key, thank God the hotel was able to upgrade the room without any additional fees. Thank you Royal Caravan, whether it was the app or the hotel's fault, I am still grateful for the hotel's extraordinary handling🙏🏻🤍
