【答案解析】Dear Manager, I an one of your customers and I am just back from the trip to Hainan. I am very unhappy about your service. First. our hotel was far from the seaside and there was no bus to take us there. Second, there was a lot of noise outside the hotel so we couldn't have good sleep. Finally, the food was also very bad. Look forward to hearing from you. Yours truly, A Disappointed Customer
