I try to go to a game or maybe even two per year but that's enough for me now, and no biggie if I don't make it. It's a young (and maybe sauced) person's game to go to every one, as I did when a student. If you have the money you can mitigate things like parking/long walks, cramped leg room via more spacious seating/suites/etc, the long day by staying over in a hotel, and expensive food costs (because you don't have to sacrifice the rest of the month's food budget to get snacks), etc.
