Myst4au, I fully understand the terms of the audit. I have contacted the MSC to see if booking a room at the location on my own dime would be allowed, and am waiting to hear back. The location is a convenient stopping point for the day, as well as a convenient starting point for the two shops I have to complete the next day on my way home.
It's basically killing two birds with one stone or, as LisaSTL said, "If you consider it a $20 to $40 discount on a room it probably makes sense as long as you can't find a cheaper place to stay without any work involved." I was unable to find any hotel shops where I could get a free room.
