But they'd likely know if they're doing this a few hours before no? I understand they can't announce this until they know day of, but it can't hurt to send a push notification for those inside the park?
Don't want to be seen as a negative, just think some extra clarification/announcement day of would be appreciated so people can take advantage. I'm hoping this is simply a test to determine the feasibility of keeping CP and a portal open past official park close.
