Don't look for a bounceback to be mailed or emailed after your stay. It is meant to get you to book another trip while you are still a resort guest. We have been going to WDW since the early 90s. Bounceback offers have been consistently available for at least the last 10 years. The only times nothing was available for the last several years have been a few days here & there as the offers changed. You have to look for them most times. Originally, the offer was on the TV resort info station. Then there was an offer sheet left on the dresser/ table by housekeeping. Then the offer was found in the paper work you received at check in. Currently, there is a packet of resort information in the room when you arrive. The bounceback offer is inside there: a pull out type page with a calendar of available dates for the offer. You must call to book & leave a deposit before the bounceback office closes on the day you check out. If you can't find the offer in your room or paperwork, call 8844 from your resort room phone & ask about the current offer.
Bounceback offers are for every resort guest. It doesn't matter who you are, what resort you are staying at, how much you paid for your current room, if you are there on a special offer rate, what day of the week it is or what phase the moon is in. If you are a current resort guest & there is an offer available, you eligible for it (Disclaimer: I am not a DVC member, so I don't know if you can book if you are on DVC points. May be the only exception.) Look thru all paperwork you get at check in & everything in the room. If you can't find the info, call 8844!
For the last several years, during the
free dining period at WDW (typically late August - early October), the offer has been free dining for a similar time frame for the following year. The bounceback during the rest of the year has been a room only discount for certain dates. Usually for selected dates in the current year, but in about October/ November it changes to dates in the next year. Again, this has been consistent for the last several years but could change at any time.
