Well, it leaves me out. I only had a short window when I could attend. By late June I just don't think masks in the heat will work for me.
I guess that's what I get for momentarily thinking I might get to do something fun.
Someone unvaccinated can go in my place.
But the visiting family will have also taken up less park resources in the course of the year.
Vacationers spend more money for each park entry (sometimes by far) AND also spend money in the parks on food and souvenirs. Disney wants it all. They want the most per capita as they can get.
