Hi ! My husband and myself (maybe some other friends too ) are planning to go to china on October , 2nd week . Can you give me an estimate how much you will charge and itinerary based on this schedule ? Leave Beijing by train (overnight) to Xian and stay 2 nights for tour , leave by train to Lhasa and have 3 days tour ; then fly to Chengdu / or Chongquing for a day's tour then train to Guilin for 2 days tour then train to Shanghai . Our Beijing and Shanghai stay are not included because my friends have been their already . Thank you very much for your attention .
