I got an "upgrade" once at a SHS. It was basically the standard room but with slightly snazzier decor and an LCD TV. I didn't care. As with others here, when I choose SHS it's because their standard accommodations are pretty nice. I see no value in an upgrade unless there's a great view to be had or there's a two-bedroom suite (do those exist at SHS?) and I'm traveling with a big enough group to really use it.
