Once in English, this application has a great potential
Unfortunately only in Chinese, but once it is available in English, anyone living and traveling in China, who is not too familiar with the Chinese language, will enjoy it. I am now using CTrip for my travel arrangements for many years and I am happy with their service. The iPhone (and hopefully iPad in future) edition would greatly help me.
