What are the disadvantages of taking a ride-sharing car to the Badaling Great Wall?

The whole family of four plans to travel to Beijing during the summer vacation. They will stay at a hotel in Wangfujing the night before and visit the Great Wall of Badaling the next day. Just checked the special deal for ride-sharing cars on DiDi, and it’s only a little over 100 yuan. However, most of the questions suggest taking various direct buses, and for four people, it turns out to be much more expensive than ride-sharing cars. But there are very few suggestions for taking ride-sharing cars, and I don’t know if there are any inconveniences about taking ride-sharing cars to the Great Wall of Badaling? Thank you.
Suggest booking a one-day tour, the most convenient option and also not expensive.

You can take the high-speed rail to Badaling Great Wall Station.
It is recommended to go to Mutianyu, as Badaling is crowded and it’s just for taking photos. There is very little time to stay on the Great Wall.
It’s not easy to catch a taxi to return, you can take the urban bus, there are several pick-up points and several departure times. You can check in at the Water Cube and the Bird’s Nest on the way back.
The bus is cheap and convenient; taking route 877 is close to the top and very convenient.
No inconvenience, saves time, just a bit expensive, but still cheaper than taking a taxi. Taking a taxi round trip is convenient, time-saving, and hassle-free.
Join a group, I think it’s quite convenient, or you can go by yourself and play on your own, it depends on your own needs.
Watch how you climb the Great Wall. If you want to walk the whole way, there is nothing inconvenient except that it’s a bit expensive. If you want to use the cable car, I suggest you book a Ctrip bus.
It may not be very easy to find a taxi when I come back.
