If you are the type of person who likes traveling, staying at resorts, never leaving the resorts, and think that the resorts and the locals you see working at the resorts are representative of the place you are visiting, avoid this place. You'll be disappointed.
If you are the type of person who likes traveling, seeing new and different things, and getting a glimpse (not the entire look) of what the location you are at is really like, go to the FSE.
You'll see a lot of the things that the negative reviews here warn you about, but that's part of the *experience*, isn't it? You can get 4-5 star service and sheltered environment that you get on the Strip in pretty much every city, but the FSE is unique.
It's worth a trip downtown.
