I could not get LeCellier or Coral Reef calling at 90+7 days for any Tier. I booked Chef LeFrance for the first dinner (3:30) for the 6:45 CP show Dec 11. I originally had lunch and decided the next day to call and try for dinner as I did not like the lunch menu and had no problem switching. I had a split stay and called on my first check in. The CM didn't want to let me book my part 2 during that call, but I insisted and she let me. (I only insisted because the online recognized my reservation and let me book my entire +10, so after telling her that, she let me make my CP ADR too). Good luck, but have several options you might be interested in. This is probably my one and only time doing this, so went with the top tier.
