Yes. the general starting point for the trip is Yangdi and then you walk along the river for about 4 hours to reach Xingping. Most of the travelers stop their hiking at Xiping and have them taken to Yangshuo by bus. Yangshuo is very developed in tourism, hotels, small roadside hostels filled the town, very easy to find one in this season, no worry. Room price varies according to different levels of comfort. I think 120 yuan is ok for a double room with shower, hot water, TV set, private toilet.
