I'm going to attend the sat of Yabo on May 5th, but the hotels around are generally more expensive. Which hotels in Hong Kong are more convenient to go there?

I looked it up for you. On May 4th, the cheapest hotels along the airport railway (in Tsuen Wan and near the airport) were all 1000 yuan a night, and many of them were full. Last time my son went to Tin Shui Wai to take the SAT, I planned to rent a hotel near Tin Shui Wai for one night. My family lives in Kwun Tong, so my son doesn't have to travel in the morning. The hotel usually costs more than 300 yuan a night, and the day before the exam 1200, so I didn't rent it. I suggest you take the earliest bus. It takes more than 300 yuan to take a taxi to the examination room in the morning, about 220 yuan (some taxis are cheap), and it takes 45 minutes at most. For example, if you leave at 6:30, you must arrive before 7:30, the traffic will not be blocked before 7:30, and the total cost of staying in a car is more than 500 yuan, which is better than staying in a hotel with 1000 yuan.
