I realize I'm biased in this, but I am hoping Disney and Universal extend all annual passes out an extra year. I think the closures are going to be longer than most people here think though. I think with every passholder impacted, and the season of the year when we prefer to visit impacted, I think it would be a gesture of goodwill and positive press, and will help with passholder retention.
It may be a pipe dream, but that's what I would like! Universal already gave me 6 months free on my last pass, and renewals add three months. I always stay onsite and buy plenty of meals and merchandise, I'm hoping the economics work out for them to offer this. Of course I understand that the parks division is hemorrhaging money as it is and this might not be feasible, financially. My mother in her 60s also has an annual pass right now, and unless they extend it appreciably, we won't be able to come back even if they open in fall. It's just not worth the risk.
