We need two more person to share expenses - usually a saden can sit four persons. That's the main reason why we prefer two more persons. I am an introvert person (that means I am not a fun person). I would like to be a good guilder to my best girlfriend but I may bore her coz I have no travel experience at all. This is another reason I need some fun people to join us. Yes, my girl friend has travel experiences but that's all in China. Some times the experience in China is totally different than that in U.S.
Looks like it is very hard to find any travel partners here. We might decide to travel by ourselves or join a travel group (that would be our backup plan coz most of the people in the group would be seniors).
Thanks for your question and have a good night.
P.S. Are you Anne Wang?
