Just to be absolutely clear, the Preferred Dining FPs won't get you "seating" either. All viewing for WOC is standing, except for handicapped and VIP viewing.
WCT WOC lunch gets you a blue FP, just like the free FPs from the GRR machines. WCT WOC dinner gets you the front Preferred Dining area (front=closer to the water). Even with a PD FP, you will have to line up early. How early depends on how good you want your view to be. As suggested above, read the first post in the WOC superthread to answer your questions.
