When the sales were in full swing and things were a lot cheaper - I had to pick between a 2 bedroom GS or a 2 bedroom ATS. In the end, I opted for the the 2 bedroom GS mainly for the noise aspect of it all, and the price. I don't mind the shows, and maybe it wouldn't be that loud, but I am a very light sleeper/napper and the slightest noise would bother me.
Also, I know it would be a difference in "class" - sky vs star. That didn't bother me either since I wouldn't really use most of the benefits that star has to offer (ie don't drink, we like the MDR/Costal, etc). To each their own though...
