I’m not sure why some people are confused. Maybe their experience was different than mine. I just got back home this morning and all the Disney bus drivers we encountered politely reminded guests to wear masks and offered disposable masks, if needed. The cast members at the skyliner also politely reminded guests to wear masks. I’m not sure if they have disposable ones available or not. My family all had disposable masks and kept one in our pocket or backpack pocket, to easily access before getting in transportation.
I've been going since last August and hadn't noticed a whole lot of slipping in enforcement myself either, we just got back a couple of weeks ago right before they got rid of pretty much all the mask requirements (aside from transportation and for non-vaccinated on the honor system). On our recent trip, just a few weeks ago, my 10 year old started walking in to Mouse Gears and forgot to put her mask back on and a CM quickly told her she had to put a mask on to come in. I also started walking in to a queue once on that same trip and completely forgot to put mine back on and was reminded quickly and slipped it back on (it's easy to forget when you're walking and talking with it off). I have several friends who have been there over the last few weeks who have talked about masks on transportation, and one who was frantic because she didn't realize she had to have them for buses and completely forgot to bring masks with her. She called me flipping out, apparently the driver didn't have any to give her that morning but the front desk CM gave her a few, she didn't realize they wouldn't let her on the bus without one. I guess some people just haven't seen enforcement so if they haven't seen it then it must not be happening, but it is happening.
Also, as far as the outdoor areas are concerned (especially with fireworks and what not), that's really a non-issue with masks since they lifted the mask mandate outdoors for all guests pretty much it's just indoors they request for vaccinated guests to mask up.
There are Hippa laws regarding proof of vaccinations. I guess a business can ask you but because of other laws, they can't refuse service. But...they can ask you to wear a mask if you don't disclose. It's a slippery slope and most places don't want the bother. I am fully vaccinated but if I feel uncomfortable around a lot of people, I'll just throw my mask on. That's all you can really do!
Well, Disney is not a healthcare entity so HIPPA doesn't apply to them. I deal with HIPPA compliance as part of my job (yay -_- ) , and there are a lot of ins and outs of it that are confusing, but until they list themselves as a healthcare or insurance provider they can do whatever they want in that regard, which so far they aren't requiring they just have to follow the law of the state of florida at this time which bans vaccine passports. Of course schools can require proof of vaccines and it doesn't fall under HIPPA either, but it is only giving dates of vaccines not personal healthcare information such as diagnosis. I personally still wear a mask sometimes since I live in the south and there are still areas where vaccination rates are low, even though 3/4 of my house is fully vaccinated (and the 1/4 that isn't is too young), this includes areas of WDW on my future trips since I brought home a bug (not covid, just a cold) on my last trip. Personal preference though, no debate, I also look dang cute with a mask so there's that lol
