Ha, I have a Tesla...it's a lease, and when it's done, we're done with Tesla. I'd thought about getting one of those stickers, but then worried that the *other* side might key the stupid thing. It's no fun driving a lightning rod, I can tell you that much

. And I know lots of other Tesla drivers....there are a ton in my area. Anecdotally, I'd say at least 50% are planning on selling them or not getting another one in the future.
As to the OPs original question. I think it's as safe on Disney property as any other place right now, which is to say....less safe than it was before. We'd also thought that Sentry would pick up someone who might key the car to identify them, but also won't participate into having someone prosecuted for domestic terrorism for keying a stupid car.
Oh well....thankfully there are other EVs out there for the next vehicle and we have only used a Tesla charger once....we charge at home and drive locally...no road trips.
