Hi YK Woo,
Warmest greeting from Daniel, your personal travel advisor at Top China Travel
First of all, please allow me to introduce myself. I am Daniel (given name by myself) Mo (family name) and work for Top China Travel about 5 years (since 2006). My self-evaluation: patient, pure-heartedness, honest and tolerant, experienced, etc... Hope you will be satisfied with my services when taking care of your China vacation :)
Thank you very much for your kindness of visiting our website and show your interests to our services. With the motto of being your faithful friend in China and creating ever-lasting memories of your China trip, we have been devoting ourselves in providing the best services possible within our power based on the reasonable price which could be adjusted according to your tour budget after our further correspondence and having more information from you.
I have gone through your inquiry and find that you are interested in visiting Tibet and combination with other tours in China (especially for World Heritage, and Ancient Architectures). I am considering the best way to save the tour cost for you since the tour duration is about a month in China. I have designed (tailor-make) your China tour program which I think may be fit to you, and please kindly check the attachment for your reference first. Since it is customized tour, you are most welcome to give us your own thoughts/comments and I am happy to make amendment according to your further requests! My target is to propose you the most suitable tour program :)
Regarding the train from Beijing to Lhasa, it takes around 48 hours (2 nights on the train) and I am worried it might be too long for you? According to my experience, the train from Lhasa to other places is the best option, which you can see the Tibet from the window in day time, and it is really wonderful views! (On the opposite, the train from other places to Lhasa, when the train goes in to Tibet, it is in the evening and nothing special to see, expect for sleeping).
In order to save cost for you, we arranged the SIC (group) tour in Lhasa (but need to meet up the fix-departure time of the group tour), it can save a lot and much cheaper than private tour! I will arrange the train from Xian to Lhasa, and train from Lhasa to Shanghai to connect with other tours!
