Check out Mousesavers.com, and search historical discounts, and click on the chart they have, which will show what has been offered during your timing, and when it was released. Most years there has been a
free dining offer at that time and some type of room discount, but every yr is different. It is usually a little slower time with kids going back to school, but with starting
MNSSHP earlier and this yr. bringing F&W to Sept. we will see. Just so you know, there are often bounceback offers available that you can book before you leave that offer a discount now for your next trip. If you do not see one in your room on a booklet or flyer, you can dial 8844 to get info.
While you are on Mousesavers, sign up for their newsletters, to get info on new things happening each month and deal alerts. You will see on their home page a list of all current discounts, and should get an email when new things are released, but I find it is not always consistent. So be vigilant and check there and here of course for announcements! BTW, if you book now, and a discount is announced, it will not be applied to your reservation - you must call and ask if they can apply it, if rooms are available at your resort. Or you can book a new reservation that fits with the resorts and dates included in the discount offered, and then cancel old one. Room discounts will only apply to dates listed, free dining applies if you check in by the last day of an offer, and includes your whole trip.
