Hi! We are going to Xian this April. We are going to take Bus 306 from Xian Railway Station to the Terracotta Warriors and Horses Museum. After visiting the museum, we want to go to the Mausoleum of Qin Shihuangdi and Huaqing Hot Spring. But we are not yet sure about visiting the mausoleum becaiuse there are alot of negative feedbacks about it. Any suggestions? Is it possible to go to multiple destinations if we buy a roundtrip ticket? Thanks!
