IF there is a Bounceback going on when you stay at a WDW resort there will be a flyer in your room that has a extension to call from your room to book. For example during the last Bounceback (this has EXPIRED) offer the flyer explained the offer and then said:
Book now by calling 8846 from your guest room. Ask about rooms at other WDW resort hotels. Offer code CDR.
You must book and pay 1 nights deposit on or before your checkout day.
Some people said they didn't have a flyer but saw the offer on the WDW TV resort channel in their rooms. Most of the Bounceback offers have been offered to WDW resort guests staying in Aug/Sept/Oct/Nov/Dec for stays at various future dates.
Just an FYI though - your ticker shows you are going in April. The regular "
Free Dining" packages (the ones where you don't have to be staying at a WDW resort to book those packages) usually come out in the first part of April to be booked for Aug/Sept stays, so if you are wanting to book that DON'T wait until you get to the resort, book it while you're still at home as soon as it's announced or the resort of your choice availability might already be gone for the dates you want....
