Wow, that is really terrible to hear.
We have been going back and forth over the Nui vs. the new St. Regis... I don't know that anything will be different at the SR, but I certainly don't like to hear about a hotel (especially such a premium hotel with such a premium cost) being "aware of", but still having issues with these occurrences...
For $1k/night, you'd imagine they could probably afford to have a supervisor observe each room's cleaning.
Sorry to hear about your loss, hope the CS Swat Team fixes things for you...
