Guests at some resorts in about half of November and all of December 2006 were subject to a marketing test program.
Two resorts had a display in the lobby; two other resorts had cards in the room. And then there are the onsite Guests who knew about the promo, even if their resort wasn't advertising it.
If you stayed onsite during the promo period, then while you were still checked in at your resort you could book another trip for between early August and late September 2007 that included free dining. Booking could be done at the booths in the two hotels with them, or by phone from any Disney resort room.
