What I do wonder about, though, is the accelerated and sudden pace at which this chance was implemented across the board, including at DVC. I am sort of musing that perhaps they have intel that we are not privy to that would have motivated this change to be brought about seemingly overnight.
It was the same way they rushed in the metal detectors, they did it a few days before Christmas and said it was a "trial". It stuck. Without enough outrage so will this. Again, unless the staff doing these searches are going through peoples luggage, it's completely useless and even then, it'd only verify for that snapshot of time, not the other 23 hours and 59 minutes of the day.
I would have no issue with having luggage scanned when checking in, though I see how it would be a logistical nightmare for including those that drive and bypass the front desk with the room ready texts. I don’t know the legalities of whether weapons are permitted on property since it’s private property but still Florida, so I’m not sure a luggage scan would be viable anyway.
Don't forget it's not just check in bags, it'd have to be every person and every bag, every time to be effective.
That's part of the reason why I said they'd have to scan every single vehicle entering property (including all persons and content obviously), A stand alone building like the Contemporary main building, sure you run everyone and everything through scanners with limited access and entry points. Virtually any of the other resorts? Good luck unless you are putting a security fence with barbed wire and sensors all the way around each resort and scanning everything at the front gate.
As to weapons on "Disney property", It isn't illegal for any licensed individual to carry a weapon on Disney property. It may be against the rules but it isn't illegal. They also can't ban you from carrying in your personal vehicle while on property, even if they tried to scan everyone "as they drove in". Anyone else remember Disney trying to ban firearms in the employee parking lots? That got shot down. The charges people get arrested on vary from impersonating a police officer or criminal trespass, no one has ever been convicted of simply "carrying a gun at Disney".
Disney has a strict no firearms in the hotels policy but that still doesn't make it illegal. It would be an interesting test case if Disney ever tried to push the issue and kick someone out for leaving a firearm in a safe for example. A colleague of mine was at the Poly a few months ago and put his handgun in the room safe rather than leave it in his car unattended for the week. About half an hour after checkout and on I4 he realized he left it in the safe. He went back they pressed him for what it was he left and he kept calling it a "personal item". He was told security would be with him when the safe was opened, so they would see it anyway and he eventually told them it was his handgun. They were none too pleased and told him next time to leave it in his car, it wasn't welcome in the hotel or rooms. Guests are allowed to check a firearm into the safes at the main reception desk, not room safes.
I often drive through the parking lots seeing the hundreds of NRA type stickers on cars and wonder what a criminals dream it would be to smash and grab all those guns... Personally I'd think Disney would want them all secured in room safes vs sitting in all those cars but not much of Disney's public face side of security makes much sense anyway.
