The security checks happened to us on our last visit in October.
We were staying at The Riviera resort. My daughter and I had breakfast at Cinderella's Castle early morning, then came back to the resort for a nap while the boys were out. The "Room Occupied" sign was on the door because we didn't want to be disturbed. While we were asleep, a woman came to the door and asked to be let inside. I couldn't see her face as she was leaning up against the door. I told her we didn't need housekeeping and she said she wasn't housekeeping but needed to inspect our room. I told her not now, then she insisted she needed to come inside. She tried to stop me as I was closing the door. I contacted the front desk, and the housekeeping manager came to our room. He said this is something they do every couple of days now. The Riviera is the only Three Palm Resort and they want to keep it that way. A little while later, a man tried to let himself into our room for the same reason. The security latch again was closed. He told my daughter he needs to come to our room every day to inspect it for our safety.
My husband spoke with a manager this time, and he used the shooting at Las Vegas as a reason and it's "the way the world is." It's not what he told me a short time earlier. Why lie to me?
What if my daughter or someone was alone in the room and in the shower? You don't anticipate these checks if the "Privacy Please" sign is on the door. Why not install luggage scanners or metal detectors? A couple of days later, two managers came to our room and told us they will schedule visits to our room for the rest of our stay. What do they think they're going to find that they need to inspect our room daily? We've been coming to Disney with our children for 20 years and never had an issue. Not one.
Like others have mentioned, we've never experienced this at any other hotel in the US or abroad.
I'm all for safety, but because someone works for Disney doesn't mean we're safe from them. How many Disney employees have been arrested for child pornography, pedophilia, and trafficking in the past several years?
Like others have said, they're not specially trained. They're resort staff. I began researching when we got home, and I was shocked by the stories on YouTube and online threads that I learned of where employees walked in while guests were undressed, showering, etc. This isn't acceptable.
*Edited to add: A week before our arrival, Disney employees were arrested in a FL human trafficking bust. There were multiple arrests last year alone.
