答案

Compared to other elements listed above, I think money matters the most. There are some reasons. First of all, even if we’re on travel, money shall be taken into account, especially for students who have a financial problem most of the time. I’ve got a friend who’s right back from a travel. He has spent too much during the travel that during the rest of the month, he has to rely on instant noodles. Moreover, not all the happiness should be obtained with the cost of money. For example, we can talk with the local and make friends with them. If lucky enough, we’ll be invited to their home and be guests. This is considered the most effective access to foreign culture. In return, next time when this foreign friend come to our city for visit, he or she will be invited also.
