Hello, I am going to travel with my family (5 pax) from Guangzhou to Guilin in July. Can I book a comfortable car or taxi for this journey?

if so where from and how much is a budget? This is because the train takes too long and bus is also 10 hours, and air is expensive for 5 people. Or can I rent a car for a one way journey? What is your advice please. Thank you.
