There isn’t typically 100K visitors in the MK at the same time, especially in the Summer when some people go early and/or avoid the middle of the day. Do you consider casually passing by someone outdoors as a close contact? The CDC doesn‘t, they haven’t changed any guidance on outdoor mitigations. Outdoors is sill considered low spread. On indoor contact it’s all relative to how many rides a day people do and how many shops and restaurants they go into. In DHS or AK it’s likely the average guest does 10 or less indoor attractions a day. MK might be double that. How close do you have to come to be considered at risk close contact? In a ride queue you probably won’t have more than a handful of people within 6 feet. Restaurants are probably the biggest risk due to the time spent in one spot. There are too many variables to accurately say. For argument‘s sake let’s say you have prolonged exposure to 100 people a day (within 6 feet and more than just passing by). It could be more it could be less depending on your touring style. My only point is it’s significantly less than 30,000 people.
As far as how many infected people are walking around I don’t think we just look at local FL infection rate. A large portion of the guest base for WDW comes from the NE where cases are low and vaccination is high. Disney also attracts a demographic that is above average in wages and there’s a clear indication that wealthier and higher educated people tend to be more likely to be vaccinated. CMs are all local, but when they brought the college program back they didn’t let kids live in the dorms with roommates unless they were vaccinated so I imagine the vast majority of those CMs are vaccinated. Again, there’s no way of knowing how many infected people are walking around and how many you come in contact with. For some people 1 potential exposure is too much risk and for others they see no issue.
