Really? And how do they access the parks? If using an AP I believe that is against WDW rules because it means they are conducting their business within the parks. Last I knew, an AP included wording to the effect that it is for personal use only. (This is why Kids Nite Out now makes you pay for a ticket for a helper to go with you, they used to enter on their own APs.)
From what i understand, they do have some written arrangements with Disney that allows them to use their APs without reservations to enter the park to help their own customers if there is an issue. It was a problem at the beginning of all of the reopening.
As for when they were doing what i described, admittedly I should have noted that i know they used to do that, not sure if they still do, but they didn't advertise their business in any way, as far as anyone thst they interacted with would know is that they were another guest, unless the person knew them. And honestly, I don't know if they still do this or not or even if they are still allowed to or not, I just know they used to. Ultimately, if they get told something is against the rules, they do stop doing it. But I know they also get permission to do some things, as to how much is allowed, I can not say for certain.
But my understanding is the following are definitely true:
Assisting their customers in the parks is allowed.
Drop off and pickup in the parks or in front of the parks is not allowed (including in the parking lots)
Money cannot change hands in the parks or parking lots.
Likely True:
Someone in the parks is having an issue and the fix is simple, they can stop to assist. For example, a CM left the
scooter in neutral and the person using it has no clue what is going on, they could stop and show them how to take it out of neutral and no, not every rental company shows their renters how to do that, although they should. They aren't doing it to make money, just help someone in need.
Also, there is a fine line between using a ticket or pass for commercial purposes and not. For example, obviously Disney is ok with the rental companies having signs on the Scooters advertising the rental company, but technically that would be a commercial purpose. Ultimately, if they follow whatever security and Disney Management says, they will be ok.
