HI, I have made 3 booking for the hotel stay on 08 Sep. However 2 of 3 rooms air conditioner have problem. At 10 pm we informed the staff about the room air cond, however they spent 1 hour to check only. At about 11.30 pm, we have requested to exchange a room. Then the staff informed only left standard queen size room and I agree to exchange as we are already exhausted. Please arrange price difference to refund for King size room and queen size room. Best regards Yah Mai
