When I worked desk at Marriott, we were told we could not call guests or contact them about lost items, for privacy reasons.

There have been instances where long ago calls were made to the number on reservation and a wife answered and had no clue the husband had stayed in a hotel that night for example so turn up the marital turbulence and the hotel staff gets caught in the middle of the proceedings.

So we were told to stay out of it, just turn into lost and found log the item and if guest called then we coudl deal with it. We wera always really good about logging and safekeeping the lost items.

We kept lost items for 3 months I think then donated to local shelters of the housekeeper who located the item if they requested. Valuable items were kept in a safe.
