Congrats, Cash!
What a great way to celebrate.
If it were me, I'd try to see if you could get a party bus. They have specific lots they park in and stay the entire game. They also let you bring whatever you'd like along. That way you don't have to worry about a DD. It could be pricey, but you're only getting married once (or so we hope!). You can probably find one to arrive earlier that 10 a.m. Either way, best of luck!
