I don't get season tickets but go a bunch during the year, if a bunch is 5 games or so. But, I have to say, the Garden is an awful place to go see a game. No not the atmosphere, which can be electric, but the place itself, the Garden, is just awful. It was not good when it opened and it hasn't aged well. I have only been to about 6 other arenas to watch an NBA game, but they were all way better than the Garden.
Celtics have like 5th highest ticket prices in the league with one of its worst facilities. Sadly, a new Garden probably won't even be discussed for the Garden for another 30 years because the Jeremy Jacob is so cheap and because, God only knows where they would build a new arena. Maybe in Everett next to the casino?
