The entrance of the underground parking lot is located in the east of wanda plaza, and the parking area is still relatively large. There are obvious directions of Carrefour Supermarket and Wanqian Department Store in the parking lot, and there are staff to guide and guide the exit position of vehicles. However, there are still quite a lot of vehicles parked in the parking lot on weekends. If you catch up, you can have an empty parking space, or you will have to take a turn. Charging standard: MS is 5 yuan per hour. If you shop in Carrefour supermarket in 5 yuan, you can get a parking ticket and a free parking for 2 hours. It is not clear whether other merchants such as Wanqian Department Store and Wanda Studios can park for free with tickets.
