Mianyang to Jiuzhaigou group travel costs

The two of us went there last summer. We went to Mianyang International Holiday Travel Agency (2nd floor of Nomart). We organized a self-guided tour, not a group tour. The price was 1,000 yuan per person. We were also students, so we stayed in Huanglong and Jiuzhaigou. There is a discount of 50 yuan, which is 900 yuan. If you go to Jiuzhaigou, one day is enough, and Huanglong is half a day, so starting from Mianyang, one *** is enough for four days. I have not heard of anyone going to Jiuzhaigou alone. 5 days travel agency.
