Hi Lyn
Greeting from Pegg, Top China Travel.
I'm so glad to help you on this tour.
I've got you are looking for a tour from Shanghai to Xian. And I'm not sure your arrival and depature cities in China. Is Shanghai the only city to connecting your arrival and departure city? If so, Shanghai-Xian-Shanghai route will be fine.
But generally, if your travel route covers more than above cities, my suggestion is:
Shanghai arrival, Beijing departure or Beijing arrival, Shanghai departure.
And we also can offer tailor-made tour for you, once I've known:
1) When do you plan this tour?
2) Which cities do you plan to visit?
3) How many days do you plan to travel?
4) Do you need book hotel from us or book it by yourself? If so, which star you want to have? 3 star fr budget, 4 star for comfortable, 5 star for luxury.
Peggy
