IMO, SOA is not worth going to at all, which, needless to say, means that IMO it is not worth 2TS credits.
The food is so-so at best. Not awful, but not all that good either. The show is just boring and dull.
If you look at the dinner show as 1TS credit for the food and 1TS credit for the show, I guess you can say that it deserves the TS credit for the food, but the show does not deserve a TS credit. If TS credits are worth roughly $30+ each, think of it as if you would pay $30 per person to watch a bad show. I personally wouldn't.
