We typically cancel or replace one of our meals in the middle of every trip. If we were thinking of canceling something with a penalty the day of, we'd probably go to the reservation anyway, just to avoid the $20 charge.

In retrospect, I think the dining reservation reminders that are now being sent out are a precursor to this announcement. That may help prevent people from being no-shows just because they forgot they made a reservation.

I'm biased in my opinion on this just because I make so many dining reservations. Disney is making it less easy for travel agents to make dining reservations. A recent site redesign took away the old TA dining reservation interface. It was kind of neglected to begin with, but it was better than the way I have to do things now. These new CC guarantees just add another layer of steps.
