So I've had season tickets on and off over the years...I'll put it this way...if you know you are going to go to a lot of games, it can be worth it. Get them to throw in concessions and parking. That was the only reason I renewed this year, since to park in the same location is 20 bucks. And I've never been to a game where I didn't buy at least two beers (I've tried, I never made it happen). Once they comp that, it makes the tickets a lot more reasonable.
On top of that, you can buy up 6 additional tickets for each game. I bought 6xGolden State and cleared around 600 bucks. Probably around 200 for each of the cavs games. So, for example, say your tickets were 6k for the season. Get comped parking and a 25 dollar beer credit (that, again, I have tried to not spend. I've snuck pocket shots into the arena and still end up buying beers), that's 1600 off the top. So you're looking at 4400. Then you go and make some money selling tickets for the big games. Lets say conservatively you clear 500 selling 18 tickets to Cle x2 and GS x1. Now you're down to 3900 for the tickets themselves. And if you're going to at least 75% of the games, its not a bad deal.
The first year I had them I was in the 200 level section, loved my seats. I would occasionally sell my tickets back to the hawks and then upgrade (for my price point, it actually ended up being a good deal). It was after doing that a few times that I realized that I cannot go back to sitting in the 200s and wanted to upgrade. Also, next season, most of the 200 section is no longer going to exist (the sideline sections are going to be gone is what I've been told). And it might seem dumb, but I like knowing I don't have to scramble on stubhub or worry about where I'm gonna park or the logistics of finding my seat. Its worth paying for that convenience.
For your situation, it doesn't sound like it would be worth it, but I figured I would post for anyone else who wants to know. You can message me directly if you want more specific information, I'm happy to tell you the positives and negatives I've experienced.
