Well, based on housing issues, Bloomington is a far better alternative, I do believe more corps were housed closer to there then they were in Indy. I'm betting if there was a possibility of it being in either location, a lot of people would have multiple hotel reservations, I know last year when I found out the move was official, I made reservations at 3 AM in Bloomington.
I recall there being a discussion at one point in time that if there was a threat of rain, the roof would be closed, I could have lived with that, we would have had the roof open 2 of the 3 days, I was irate in my hotel parking lot on Thursday when I realized that there was a 7% chance of rain and the roof was closed.
