Here is a website with a few more lodging options.

The Super 8 in Killen is only about 5 miles from the stadium and you might have an easier time getting reservations. The only problem is that they are building a new bridge and it is a construction zone, so the speed limit is 35 mph, but it isn't enforced on the weekends, so I wouldn't worry about it.
You might want to fly into Huntsville, it is usually cheaper and it is only about an hour away. If you did want to travel by train, I think there is a station in Birmingham which is only about 2 hours away....
Good luck next week. We hated to lose, but still wish you the best.
BTW - most of us have a full set of teeth down here and marriages to non-blood relatives.
Have a safe trip and see ya at the game!
