I remember hearing of an ADR hack for avoiding the cancelation fees within 24 hours. The tip was to reschedule the ADR to a time beyond the 24 hour window and then cancel it. We've got a large group heading to WDW in the next few weeks, and I'm wondering if anybody knows if this tip still works, as we may need to be flexible given the current situation and the cancelation fees would be quite a bit of cash!
