Hello

I stayed there in November at the New Plaza Hotel (opposite the railway station), there is a travel agent just outside to the left of the building, that sells very reasonable li river cruises 250 Yuan including a small lunch. There are other places that sell Li River cruises (at Guilin Airport and most hotels), they are normally about 400 Yuan, include a larger lunch, and transportation to hotels. The Li River cruise is 4 hours long. Once you reach Yangshuo dock, there is a 5 to 10 minute walk to reach the electric cars. The electric cars cost 10 Yuan, and take you to the tourist parking area. There is accommodation close to the Li River, which is advisable to book before you reach Yangshuo. There is accommodation a further 10 minute walk from the departure point of the electric cars. There is a bus that takes you back to Guilin, costing 15 Yuan, and bus trip is 1 hour 20 minutes.
