As a reminder, when you sit in a corner section like 304, there are so many seats per row and that's not good for fans with over active bladders. If you're one of those fans and you know who you are, steer clear of section 304.
There are many more sections that are better seats overall than 304 so I wouldn't waste my money. I would also make sure to eat before the game. The Billy Goat tavern isn't even a mile down the street. (There isn't much to do right next to the arena).

I enjoy sitting on the 300s because all I need is a solid view of the ice to enjoy the game. I don't need to sit right upon the glass because believe it or not, it just isn't that great of a view. I also do not need a waiter to bring me my food, in fact I enjoy walking around on the concourse and people watching while I sip on my $9 beer.
