Also, you have stated that you have hotel rooms booked all through the state. One lesson learned from when I have chased a tour is to have as many rooms booked in the same hotel as possible, even if it means some more driving before/after an event. When you go from room to room, you have to get up get packed and out of the room by 11. However, you cannot check into the next room until 3. Finding something to do with the 4 hours in between can sometimes be a pain, especially when all you really want to do is to take a nap. Besides the wasted time of packing up and unpacking every day, you have to waste time checking into each motel.
For your off days, you may want to look to see if there is any professional baseball in the area. I know that a lot of drivers and TV guys go watch baseball on the days off.
Staying in the Indy area would be good for most of ISW except for perhaps L-burg and Haubstadt. Plenty to do and see in the Indy area and not that long a drive to most of the tracks.
