Nice, was just there last week. Definitely not as quiet as in this video, but not super crowded. It's super gorgeous at night, fountain shows and drone shows were nice little bonuses. A great view of the Great Wall Of China. Very nice getaway from the hustle and bustle of Beijing city. Wish I stayed more than just a night. Totally worth visiting !
You may book a bus via wechat or by going to their website, but I can't understand Mandarin. So you can just go to the bus station early. And yes, they do accept cash
