These are my personal maunderings and meanderings and carry no official weight, and if necessary, I will deny any part or all.
Officially you can't bring the knife into Disney or California. There is a bag check process where bags are checked. People aren't patted down, or pockets checked. All the people that I know of, who have been turned away at the gate for knifes were spotted because they had a big ass clip showing.
Today for the first time, I am aware of, (and this is not necessarily indicative of standard procedures it might be just the first time somebody let us know about it) and the first time several other employees are aware of, they checked if an electronic device was functional and when it didn't turn on had the owner return it to their vehicle. Not sure what it was, about 5x7 in size. The owner opted to take it back to their car.
Note 1 : Today was the 60th Anniversary, there was the shooting in Chattanooga yesterday, and today IIRC was the last day of Ramadan. What was the behind the decision to be more thorough on the checks. I expect the first reason almost entirely.
Today, I also saw a service dog in a wagon. Large shaved area and dressings. They were waiting on the ramp to get on the trams. There was a lead and a few other employees talking to them, this could just have been seeing how things were going with one of the regular visitors and their person. I have no idea what the disposition was. I expect the answer was to let the Main Gate people work it out.
The initial screenings and decisions are made by the Main Gate personnel. If necessary, Supervisors, Managers, Security and APD can get involved. Getting Security and/or APD involved is not a good thing.
Note 2 : When an item on the "prohibited" "list" is presented at the entry gates or bag check, the employee will inform the guest that one or more items, is inappropriate and will not be allowed in to the park(s). Some items, the employee may suggest that the items can fit in to nearby lockers and stored there. Primarily this is usually smaller coolers and other food. Generally the guest is informed that the object is not coming in, disposition is up to the guest. Although the real answer to the question, "Do you want me to throw this thing away?" is "YES, you MORON, did you even think to call or look up whether you could bring your World's Largest Off-Road Wagon in to the parks?" the official answer is, "Sir, the item is your what you decide to do with it is up to you. Most people take them back to their cars. (motel rooms, etc)"
Wagons (or other wheeled and normally pulled objects) Aren't going in unless they are being used for a medical or similar purpose. Carrying oxygen bottles, rigged up to carry a disabled child in lieu of a wheelchair or gurney, etc. Because you brought enough stuff to fill a small station wagon doesn't fly.
Weapons - Normally asked to return it to the vehicle, I have seen guests escorted by Security back to ensure it was taken to the car. I expect the guest raised a stink. Security is not part of the normal practice. I have seen people try to take real bows and arrows in to the park. (Security and APD handled that one.) I have seen kids with the toy gun that was purchased in the park before lunch get asked to return it to the car. The involved employee was reminded that guests may return with purchased items. To the best of my knowledge the only concealed carriers that are allowed on a regular basis to carry in the park are members of local PDs or on-duty officers. Non-sworn carriers can't. If there are lockers, there aren't that many, it's a hassle. (Part of this is that there are in reality extremely few civilian CCW in CA. whine about the word elsewhere. It just doesn't come up all that often. Don't screw it up for others.. The other aspect is safety. A pistol that may pass simple drop tests that is launched from a ride may not pass that drop test. It may also hit somebody..
Selfie Sticks - Officially BANNED as of two weeks ago. For a short time, duration un-announced, guests will be allowed to check them in at Lost and Found. This is an attempt to accommodate those guests living under rocks that didn't see or hear about the ban on media. The practice will not last, Lost and Found has neither the space or people to accommodate it. If found with a selfie stick in the park, the guest will be escorted to Lost and Found for storage. Any objection the guest will be escorted out. Rides and guests have been damaged by these things
Commercial grade cameras and other recording devices - Allowed after coordination with Media Relations (You ain't goona make money on the property without the mouse getting his cut.)
Animals, pets- go to the kennels. Must present record of current vaccinations. The list changes and comes from the County. No record or missing vaccine, no boarding. The only one who can make any exception is Walt, and yeah, he's dead. The county can and does make surprise inspections. Fail the inspection, immediate closure. Hence, no exceptions. Historically any legal non-venomous pet was allowed if the fit. If they didn't fit Circle D would take to the "ranch". Apparently larger animals are no longer accepted.
Animals, Service - Allowed in parks. Supposed to be certified, which is still in limbo.
Drugs - A good way to get immediate involvement with Security and APD. Not a good way to start your day at the happiest place on earth.
Dress Code - Nobody likes to enforce it, but see through garments, overly revealing garments, sexually or politically or both inappropriate messages, etc, adults in costumes, especially skimpy Princess costumes, etc. Using a little smarts goes a long way. I have seen older female German guest wearing too transparent tops with no bras (my eyes). I have seen a few boobs get through
