After much deliberation, we decided to buy the route Beijing, Shanghai, Hainan, Hong Kong. Arriving in Beijing, we settled in the hotel with our group of 10 people. I note that throughout the rest the hotels were 5 stars and fully corresponded to this category!
Stayed with my wife in August. The rainy season manifested itself in one small rain that lasted 2 minutes. On the spot they paid 600 bucks for a superior room, so the standard seemed very modest, if not bad.
