Been to many shows here and like any show and arena, it's a hit and miss. The place is clean and the ushers are organized. The concession area is sometimes used for photo opp, merchandise sales (meaning, more $$$$ from you) and other marketing blitz. The last time I was there for Katy Perry show, Virgin Mobile sent a bunch of men in skimpy pink shorts.
They were supposed to be eye candies but my eyes were sore after that. It's the pink shorts guys... they're too bright.
Parking is horrible so take Toronto's slow "rocket", the TTC, if you plan to keep your sanity. Parking in the area can go up as high as $25 at certain events and you're not guaranteed a spot.
Sections 101 - 103 (may change) are the best sections to choose as these sections seem to be always facing the stage.
If there is one tip of advice: if you plan to be cheap and buy the cheapest ticket... bring binoculars. Or just buy the artist' CD because you won't see a thing. No kidding. The band will be as big as tiny dippin dots.
