They're usually pretty lenient about staying after the game. You can get away with 3+ hours after the game is over at least.
If you guys are drinking, you damn sure better have a DD. Don't risk it, there's too many people out there to be driving shitfaced.
So my recommendation would be to figure out a DD and get there as early as possible and enjoy it all.
Standing just depends on your section. Some sections stand the entire time. Some sections get pissy if a small group is standing and no one else is. Just go with the flow and don't be an asshole, and you'll do just fine.
