The ONLY thing I would tell people to consider is if you want to get home fast after the game, it can be a little frustrating sitting on the bus waiting for everyone to show up so it can leave the stadium and take you back to your car. If it's a continuous shuttle system, then it won't be as bad, but if it's a "you got this bus number there and you need to get on that bus number on the way back," you will have to wait.
Years ago, we did a tailgate/transportation for the UCF game and I remember sitting there thinking how far down I4 I'd already be...
But if you're not in a hurry, by all means do it. I try to do all the tailgates put on by USF for away games and you can't beat the atmosphere if you're a smaller group that doesn't want to bring all the tailgating equipment on the road.
