Update #2
Well the GM returned yesterday but I have not heard from her as of yet. The last person I did speak to was extremely defensive almost to the point of insinuating that we had place the feces there ourselves.
As far as compensation, I believe that three free nights would be appropriate under the circumstances as it was a two bedroom unit and five adults total were inconvenienced. That's not evening taking into account my embarrassment in front of my guests.
Will update again when/if the GM calls.
