A bounce back offer is a special discount that is only offered to Disney resort guests while they are staying in a Disney resort. The offer is usally located in the Be Our Guest information booklet that will be left in your resort room. You would call the phone number listed in the brochure to make your bounce back reservation. The available offers are usually more generous than any offer to the general public, which make them a very good idea to book. You can always change dates and or resorts of your bounce back reservation if availability still exists. Once you check out of the resort the offer is no longer available to you.
The bounce back offer will be available during your December trip. If you don't see the brochure in your room, then you can dial extension 8844 from your room phone and ask about it. Some guests remove the brochure and housekeepers don't always replace them. Your offer would most likely be a room discount for select dates and resorts in 2016. Historically, dates after Easter have been included in the bounce back offer.
