UPDATE on the Sheraton Sonoma
After reaching out to the hotel a second time, I received an odd email around 10pm in the evening from a member of the management team who indicated how busy it was "as I can see" by her emailing at that hour... She then added she was checking with her team regarding the concerns I raised. A week passed, no follow-up.
I then reached out to Corporate, and received a response within 48 hours. Stock "we're sorry" reply, with a fairly generous number of points.
I'd like to know how (if) Sheraton Sonoma will take corrective actions going forward. The corporate response and property non-response fell short of this.
