Remember, it is a priority seating and not a reservation for a reason. The system is deigned for some people not to show up. They don't hold a table for you and make others wait when you *don't* show up. They just put you at the front of the line when you *do* show up.
That said, it is courteous to cancel if you know in advance! We always call when we can. But, if you get stuck in a line or just get too tired and by the time you get back to your room, it's too late to call, it's OK. You don't have to feel guilty.
If you know in advance, it is better for others that you call an cancel. Then they can book your time slot. And certainly it seems very greedy and inconsiderate to make several seatings using fake names! But the honest, last minute change of plans are expected and excepted.
Hope that helps!
