I doubt they just toss out parade floats that they spent a lot of money on. The Maleficent float? Doesn’t fit as a cavalcade float, and highly unlikely to just be scrapped for metal. They restarted the parades in the Asian parks, we just haven’t caught up to what they’re able to do safety wise. Same with fireworks.
Everyone that knows the name “Chapek” knows he’s money first, have for quite a few years. This isn’t new just because he’s the CEO. Shows in resorts are the Disney experience. While they may not come back for a while, and not the way they were, they’ll return one day. If Disney becomes rides and restaurants, there’s nothing separating them from being a Cedar Fair or Six Flags park.
The bare minimum isn’t what they want to offer, nor is it preferable for the guest, but it’s what they can do right now, budget wise and safety wise. I would bet that the vast minority of people are leaving the parks wishing they could trick or treat. Sure, that would be a nice addition, but I think most would agree that if it’s one year without trick or treating in the parks, it’s a very minor inconvenience. We’ve almost been in the pandemic the same amount of time between now and when Halloween starts again at Disney. Much of what is noticeably gone from the park experience will be back before we know it. The parks being closed seemed like an eternity, but they’ve been reopened almost as long they were shut down, and it feels like they’ve been open for much shorter.
