For now, I reserved a room at the HIX in Ontario, Oregon for the night of 8/20. It is about 90 minutes from BOI.

The asking price was $681 but I paid 15K IHG to reserve the space for now. I will get a room the night of 8/21 in BOI, or more likely, just fly back that night after the show is over as totality is around 11:30am in eastern Oregon.
