How much does it cost to travel to Chengjiang for about 3 days during May Day?

Depart from Kunming and take a bus at Xinnan Station. Tickets 16 yuan (including one yuan insurance), go back to 32 yuan. If you stay in a scenic spot for two days, a 2-star hotel can go to 200 yuan at 80 per night. You can also go to a private place. The facilities are almost poor, but they are absolutely clean. Each person needs 100 yuan for dinner. It depends on how you play for three days. 500 yuan is enough, the most practical.
