My wife had some money stolen from our room at the Renaissance Wailea Beach some years ago. We went to breakfast and she left her wallet in the room. Some money was left in it to make it harder to discover, but we found it shortly after we returned, it could only have been an employee, housekeeping or other.
The hotel was not at all helpful or even sympathetic and did nothing.
Now I/we always put out the do not disturb sign, use safes if available and/ or take jewelry/money with us.
