I have never even contemplated putting anything beyond passports, money and jewelry in our room safe. But we trust our maids and staff implicitly. We once dropped a fifty dollar bill under the bed w/o noticing. One of the maids found it while doing the midweek cleaning and left it on the nightstand in the master bedroom where I couldn't help but see it, and then asked me the next day if I had found it and told me where she had found it.
