I will be arriving in beijing sep 16 and returning back Oct 4 so i have bout 2.5weeks in china. My plan is to spend first week in beijing then on Sep 22 take overnight train to Xian spending 2or3 days not sure then overnight train to Shanghai spending 2 days (i heard from other forums not much to see in Shanghai despite its size but The Bund will be a must) with a side trip to Zhouzhuang then go to Shouzhou for 1 or 2 days not sure then train back to Beijing
Please give me suggestions on best possible route and time allocated any modifications or changes from my plan will be apprecitated most importantly starting and finishing point is Beijing.
Please advice also on whether i can find cheap hostel or budget hotels while in shanghai suzhou and xian as in can i just reserve hotel while im in actual city rather than booking online as i am not sure of the exact dates(For Beijing i will be staying at a relative so that should not be a problem)

Is the plan ideal that way or should i cut few destinations as i originally thought to do Beijing Xian but then it seems that adding Shanghai Suzhou together would make it better as i am a first time traveller to China. Thanks in advance
