The stadium is in a great spot in San Diego and you couldn't feel safer if you were in your mother's arms. There are also plenty of security in case people get out of hand but I have never seen a situation where they got involved.

No problems at all. In fact the locals are very accommodating. Yes, they are very passionate fans however, just like us, they were out for a good time. The only thing to watch is bag snatching, although we did not experience it ourselves, they do warn you when you enter the ground, and in my experience, if the stadium has to issue a warning then it must be a problem.
