visit Chaka Salt Lake and Qinghai Lake in May 2019, arrived to Xining by Train at 1045AM.

And I booked return train ticket from Xining next day on 02/05/2019 at 1525PM.

I only have time to visit Chaka Salt Lake and Qinghai Lake
at 11AM(01/05) to 3:25PM(02/05) and we are 2 people.

My question is
1. Can I able to rent a car or rent a car with driver for the trip?
2. Can I stay in a traditional yurt tent near the Chaka Salt Lake or Qinghai local Lake village?
3. Can I join any groups? or how can I get people to the car?

Thanks
