I&amp;#x27;ve stayed at PH, TI, and the Venetian over the last 3 years for conferences and personal travel, I pass on housekeeping the whole week, and there have been no security checks like you describe.</text></comment>

It sounds like they &amp;quot;do inspections&amp;quot; every day of the year.&lt;p&gt;&amp;gt; Since the festival shooting Vegas hotels have a policy of entering every room every 24 hours&lt;p&gt;&amp;gt; so now they do inspections when BlackHat&amp;#x2F;DefCon is in town because they don&amp;#x27;t trust their own tracking systems&lt;p&gt;What&amp;#x27;s the difference between these two statements? It sounds to me like the only point is that they have a manual ledger to track inspections, which is probably for the best, given that any would-be domestic terrorist would surely know how to use Google and find this information too.</text></comment>
