Ok, I have read zillions of reviews on Xian. It seems that most TA's say 1-2 days are all that is needed, even the private guides. I don't know if that comment is for people that are totally rushed for time and want to see the most in what little time they have or it is based on a slow tour of everything. We have two or three days and don't want to be wilthout something to do on the third day if we have already been to the TA warriors and all the sites in the city. What do you all think? We are actually quite fast paced and don't like to sit too ideal at least during the day.
