Seats in the Air Canada Centre are kinda close to each other. The guy beside me big so his elbow kept touching my arm so it made it extra uncomfortable. I'm sure you'll have better luck than that as that's an extremely rare case.

It gets very busy and packed so lots of bumping and brushing into people. They change the escalator direction depending on the flow of traffic which I found pretty neat.
There are 28 total rows in this section so it's a big section but all of the lower level sections are pretty much the same size.
If you can afford the tickets, you are going to have an amazing experience, that's all I can say.
