Hi, Monique! The buy four, get three free deal was an incredible offer, and I do not recall the last time Walt Disney World has offered a promotion like this. I have no information regarding this offer being repeated, but keep your eyes on
www.disneyworld.com for all of the latest offers.
It's tough to predict when offers may be released, and it's hard to know what they will offer. Free dining has been very popular, and it's a deal that has been repeated several times over the past few years. It seems to be offered for a late August, early September time frame, and the offer has been available for booking in the spring for the past couple of years.
The best place to keep on top of the information is the Walt Disney World website. If an offer is available, you'll find it there!
