YariGuy helped me book a hotel in Japan last week because his rate was about $40 less than my quoted rate. This was due to the fact that many hotels in Japan use the person charge concept and the default is 2 people (I would not have wanted to stay in that room with a second person, no matter how much I liked them). On his version of the Trip app, he was able to select "1 person", but I didn't have this option on mine (neither Trip nor Ctrip). After about 3 days of back and forth emails/chats with customer support, I finally threw in the towel and simply used his reservation. They gave me $40 in Trip Coins for the trouble.
