Earliest to reserve Breakers for 2018?

Howdy everyone! It's been a long time since I have made it up to The Point, but my son is graduating High School this next year and has suggested a Senior Trip to Cedar Point. We will likely have a party of 5-8, and are wanting to stay at The Breakers. Does anyone know when 2018 dates will open for reservations?

It used to be February/March until Mr. Ouimet took over, then it was January. Last couple of years it's usually during Halloweekends, obviously they'd wait to see how the hotels performed during the regular season before setting a rack rate for the next.
