We used it on our trip last month. There aren't as many locations as I would have liked but my kids still like meeting characters so we got Photo Connect pictures at about 8 places. Quality is similar to WDW.
My daughter was to busy dancing to pose for a picture...
Plus the photos while you're on rides- if you like those, it's definitely worth it. There's a "couch scene" in Simpson's area- we got 4 pics with various backgrounds there ( I THINK 4 5x7 was $30). We buy the MIB one every time we go- we take it WAY too seriously. I say if it's your first trip- do it, but make sure you get your moneys worth (4 pics).
the places I can think of:
IOA- Entrance
Hulk coaster (when it re-opens)
Marvel meet and greet
Spider-Man
Ripsaw Falls
