The four of us want to visit Pingyao Ancient City, Mianshan, Wang Family Courtyard and Qiao Family Courtyard for two days. How much will it cost? By the way, are there any delicious snacks?

I have been to all the places you mentioned except the Wangs' Courtyard. You can go to Taiyuan first (train ticket to Taiyuan 100 yuan). When you arrive in Taiyuan, you can go to Changjia Manor, which is better than Wang Family Courtyard. You can get there by bus from Taiyuan. The fare is around 3 yuan. I don't quite remember the fare. Looks like 40 yuan. It is possible to raise the price now.

Then the next day, you can visit the Qiao family compound. I don't know if you are driving or something. It's convenient to drive, because you can pass by the Qiao Family Courtyard on the way to Pingyao (in Qixian County). If you don't drive, you can take a bus from Jiannan Bus Station in Taiyuan to Qixian County. It seems that the entrance fee for the Qiao Family Courtyard is 40 yuan, which may be higher now.

After visiting the Qiao family courtyard, you can go to Pingyao on the same day. In Pingyao, you can stay in Guangju Hotel or Yunfeng Hotel (Samsung standard, these two are ok, but the price of international hotels is high). You can go to Pingyao ancient city the next day. It's quite big. I suggest you take a day off to go there. The price of the ticket is 120, which is a through ticket. You can go to several banks and escort agencies inside and come back to rest after the transfer. At night, you can see the night view of the ancient city and the beautiful bars, because you don't need tickets to enter the ancient city directly without looking at the money houses and escort agencies inside. The night view is beautiful.

Mianshan is in Jiexiu, and there is CMB near Pingyao. Tickets seem to be around 100. Mianshan is very big. If one day is not enough, you can live on the mountain. The hotels are all good and the facilities are very good. You can play the front hill the day before and the back hill the next day. It's just that when going up the mountain, traffic jams are easy on holidays. It's best to go at ordinary times.

I don't know if you are satisfied with my answer. Have fun!
