not really, no. I'm sure they considered everything, like having airport-style security to go up to the rooms, which is even more invasive. This way if there is another incident they can point to their policy and say "see? we inspect every room every 24 hours. We can't have a security guard in every room, but we at least tried"
Is it not possible to create new policies that are effective while not compromising the privacy of your guests?
