IZUMI Reservations Closed

I'm 2 months away from sailing and I can't book a reservation for the Izumi sushi restaurant. It doesn't show up on my Cruise Planner. I called and they said the restaurant is totally booked (except for the Hibachi, which is still available). Is it small enough to book up full this far in advance? Should I keep checking to see if it opens up again if someone cancels?

Since it's ala carte (and this a zero charge upon reservations) I have a feeling people reserve it and then no show.

They only offer a percentage of available slots before the cruise. Go to any restaurant when you board and schedule a time on board.

I would tend to agree with this.
