Hi, I am planning to visit Xian middle of March, some questions:

1. Well, most popular scenic areas open to the public every day, such as Emperor Qinshihuang's Mausoleum Site Museum, City Wall, Big Wild Goose Pagoda and Bell Tower & Drum Tower. But there are some scenic spots close on specific days. For example, Shaanxi History Museum is cosed on Mondays.
2. Day 1: Emperor Qinshihuang's Mausoleum Site Museum - Huaqing Hot Springs - Bell & Drum Tower - Muslim Quarter
Day 2: City Wall - Wild Goose Pagoda - Tang Paradise
3. Generally speaking, the one-day tour of Terracota and Huaqing Hot Springs costs CNY 500 per person based on group size. As I know, TravelChinaGuide provides this kind of itinerary. My friends booked from them last year. Their service is excellent. So you can join in a tour of this reliable travel agency. If interested, their contact information is traveltravelchinaguide.com.
