You are a local guide. After checking in at the hotel, one of your tourists wants to change his room to one with lake view. He comes to you for help. (入住后,一游客想换房到湖景房。和游客进行对话) Your dialogue with your tourist will include the following parts: A. You clearly understand what the situation is; B. Your willingness to help; C. The actions you are going to take. (Reference: Mr./Ms. xx, you want to enjoy the lake view in your room, so you'd like to change to a room with lake view. Is that right? I understand what you mean. I'll ask the hotel whether there is such a room available immediately. If there is a room available in the same grade, I'll help you to change it at once. If it's an upgraded lake-view room, the extra cost will be paid by yourself. Hope you understand, Mr./Ms. xx.)
