No, of course not. But it's a start.
I'm completely inexperienced in most things Disney, so take this for what it's worth. But I don't think they'll be offering codes for June, July or early August. Just about every school in the country is on vacation, and that's when so many families plan their vacations. There's no need for them to lower prices to lure families into the parks or the resorts; we're going anyway.
The reason that it starts again on Aug 10 is that so many schools (down South anyway) go back then. Is there any way you can change your dates to mid August?
