We are lowly silver and were able to book specialty dinners 120 days (125 for club balcony and up) out including main dining rooms. HOWEVER book the venues with set meal cost like Teppanyaki 1st, if not system will try and charge you for those, even though you still have open dinners. I'm not real good with math, you might be inside the 120 and those advance reservations go QUICK!! However it's well documented there are at least 1/2+ the reservations held back until cruise day, just don't hesitate finding were to book on board and go there 1st!!!!
