The above is from the Mousesavers site. I only copy/pasted the dates for early to late summer. If you look and see....the majority of those discounts came out in March and April of 2018. The latest one hit on May 29th. I would think if Disney was doing any more summer discounts they would have been released already. It's April 16th and nothing has happened.

I mean even FL residents look like they are out of luck as our discount last year for late summer came out on 4/17. AP holders saw it on 4/10. Now Disney could very well just blow everyone away and release those codes later in May, but I'm thinking why would they wait when there are plenty of rooms out there to book and guests are waiting?
