I called at 180 days and we wanted Le Cellier for our 10th day so that we could get a good dinner time for us aka not 4 or closing time. I remember I said Sept 27 (Friday, also EMH PM) and the CM said something like- oh I'm sorry it looks like there are no more openings for dinner on this date the only, and LAST time available was 1:50PM. I was completely stunned! Turns out, she got the date wrong and was looking on Sept 20. When she looked on the correct date, we got whenever we wanted basically!!! Same with all of our restaurants (within 20 minutes of our desired times).
My point is that even at 183 days, it basically all booked up. We like to go but wouldn't be devistated if we didn't. It's not dire, not even in our top 5 but we still go because we go for over 2 weeks and like variety, I just don't understand why the HUGE HYPE for this restaurant, it's good but not THAT good.
My tip: When you make your ADRs, definitely without a doubt, do it at 180 days and put the harder to get ADR restaurants toward the end of your trip. Less people are eligable to make reservations the further out you go.
