Perspective from a "WDW Bus Driver" - Make sure you bring about your big grain of salt
Back in the mid-late 90's I worked at
Disneyland, where during the summer of '96 the crowd levels each day were about 90k-95k, due to the Main St. Electrical Parade "Glowing away forever". To this day, I've never seen Disneyland as busy as those times. But what it does is give us an insight into what Disneyland's true capacity is. I know that these days when we hear 65k, it is a truly busy day, but back in 1996 we didn't have fastpass, or park hopping(no DCA in 1996), which has contributed significantly to the overall feeling of "crowdedness." So one has to wonder what number they will use for capacity. If like WDW, they do away with FP, they could easily use a 99K capacity and base the percentages off of that.
Also, earlier this year, when businesses were opening back up with x% capacity, my gym's owner contacted a friend who was a fire marshal to see what the capacity was. In a 6000 sq/ft facility, the fire marshal said the capacity was 220!! I almost busted out laughing when I heard that, but the owner used that number.
Taking all of this into account, the 15% and 25% capacity could bring in many more folks than we think. Of course, the demand is going to far outstrip supply for at least a few months, which leaves us with the question of how they will adjudicate access. I'm for hoping its a lottery just like the DVC Moonlight Magic, where everyday, you get on and are assigned a spot in line.
