Not sure what is confusing. You quoted Wood Nymph, who was responding to a question about booking Sept 2017 in May 2016. She provided the correct answer. Offers will stay for 2016 most of the year. In mid - late August,
free dining for 2017 & mid - late October, the 2017 room only offers should be available IF Disney follows past trends. It really is simple: during the fall free dining period, free dining for the following year has been offered. Room discounts are offered most of the rest of the year, changing to the following year sometime in October. Call 8844 anytime you're there to check the offer. Again, this is past practice & no guarantee Disney will continue it.
