I don't believe any of them "require" priority seating - but we have always gone ahead and made reservations. I am thinking October will be a bit less crowded - but once that October calendar is posted I will be making PS for the Stitch breakfast, as well as dinner one night in DD. With the PS is is nice, no waiting for a table - this is great for us with the two little ones - but I am pretty sure they all take walk-ins.
