+ 10 points - Lots of freedom in your day. If you feel like doing something, you can just do it. If you feel like resting, you rest. Yesterday I felt like walking a long way to the War Memorial rather than taking the subway. And I could do it.
+ 15 points - You meet more people. Because you are alone, you are forced to go out of your comfort zone to become acquainted with people. I have gotten to know Koreans, Australians, Canadians, Vietnamese, and Malaysians.
+ 15 points - You have a lot of good stories. Because you have to meet new people, you end up doing things you would never do. For example, last night I watched Australian rugby in an Aussie restaurant that was filled with Australians.
- 60 points - You are traveling alone.
This might be exaggerated. . .
