Sorry to revive something of a zombie thread, but Disney must at least be thinking about bringing DAH back this summer, right? These events were profitable pre-Covid, so I don't see why they wouldn't be now. This seems like an easy and obvious way to make up for lost profits. With no Fastpasses during the day, shows, parades, fireworks, and characters still on the shelf, and crowds continuing to grow, long lines this summer seem both inevitable and unavoidable. So demand for ways to enjoy the parks and rides without the long lines would seem to be sky high. Now that Disney has called back furloughed cast members, and appears to be advertising for additional hires as well, it doesn't seem like these events would be hard to staff. I don't see any reason not to bring them back.
Hoping we might hear something soon!
