Pre-game action & parking for Camping World?

We're a group of 6 flying in from Houston Sunday morning. Rather than screwing with 2 Ubers every time we want to make a move somewhere, I rented a Pathfinder (allegedly seats 7) for $65.

Any advice on Parking for the game?

None of us have been to this stadium before so was wondering if it's best to park downtown and just take the shuttle or if that's a isht show and we're better to just pony up and pay more to park closer to the stadium. There are resale parking passes available but they are pricey. I assume you can just find some random lot for $50-$100 but maybe I'm crazy. The wimenz are high maintenance so a mile walk isn't going to cut it...

As for Pre-Game, is the Fan Fest likely to be anything worth attending or should we just find a bar/restaurant to kill some time?
