The exact same scenario can cause one person to feel unsafe and uncomfortable while another remains completely unbothered. Is one person wrong and one right? No. Our perceptions that carry over to emotions and thoughts, which then turn to action or inaction, are based on many factors of previous trauma, age, number of prior experiences, and many, many more factors. To one, if they’ve never been the victim of a home invasion crime, they may still feel safe leaving a door unlocked during the day and never give it a second thought. Another person who has been a robbery victim may experience great distress mentally and physically at even the thought of an unlocked door. Are either of them wrong? No.
The room checks are a moderate response for those who find reassurance in knowing this is done. To those who object to them, that’s ok too because their experiences are different and honestly in the total amount of those performed, very few result in guest interaction.
But it’s important to remember, fear is not a negative emotion or trait. It is healthy, and even necessary, for survival. To minimize another's level of fear is insensitive and to live in excess fear is unhealthy. But what is moderation? No one knows because it’s different for every one of us.
I have only experienced a security room check maybe 3 times in hundreds of days at Disney resorts. I personally don’t think they are super effective but if it gives others a a sense of safety, I don’t find them to be intrusive or a bother.
