China: To go or not to go, that is the question

I’d like to take this once in a life-time trip to China to see a total solar eclipse.  It is sponsored by the Academy of Science, so I believe the trip would be educational as well as fun.  But, in this current economic environment I am really not sure that spending some major money on a 14 day holiday is economically responsible. My vacation savings account helps me to put a litlle bit aside each pay period.  It comes right out of my paycheck before the DD, so I don’t miss it.  Just not sure if I want to spend the money.
