IF we have pre booked priority seating, what happens if we turn up at the restuarant and find a long queue waiting. Do we have to join the queue or do we have to bypass it and go straight to the front. I'm just a bit worried because we have to arrive I think about 10 minutes before the PS time and I'm worried that by queing up we may be late. This will be our first time at a Disney Restaurant so I don't really know the procedure. Thanks
