Yeah, I think there is some politics involved there more than just a concern for health. Canada still has travel open to practically all of Europe, where COVID is right now spiking out of control, at rates beyond even what's happening in the US. I understand Canada may care more about what's happening in the US because they share a border. But it's ridiculous that they are concerned about Canadians going to Florida but says nothing about them going to Europe.
In any case, any international travel is going to be difficult until there is a vaccine widely available. A lot of people just simply don't want to travel right now because they are scared. Those that do and aren't scared are either effected by border restrictions or they think the safety measures are ridiculous and overblown. (ie" Don't want to go to parks with a mask on).
Disney also claims that it's 25% capacity. I know someone that recently went. They go to Disney a lot and are DVC members, so they know when the parks look busy. They said there is "no way" it's capped at 25%. It's more like 50%. They said they asked a cast member about it and they were extremely tight-lipped about it. So Disney may be cheating that number a bit in order to help their revenue.
He also did the license plate poll (walked through the parking lot to see the license plates are from). Most are from southern states. Lots of Georgia, Alabama, Tennessee, Carolina, and Louisiana plates. Of course lots of Florida too. Also surprisingly a good number of California plates. Looks like California people are going to Disney World to get their fix since
Disneyland is closed. New England plates were noticeably scarce.
