Hi,

We want to travel from Guilin/Yangshou to Guangzhou by sleeper bus (we found the schedule above)

First we would like to take the boat trip on the Li River from Guilin and exit at Yangshuo.
Question 1: Should we go back to Guilin and take one of the busses from the Chief Bus station or can we board at Yangshou?
Question 2: Should we make a reservation or can we simply hop on? If we should make the reservation, where can we make the reservation?

Thanks! Gijs
