Disney world bounce back offers. Help
They are in the packet found in your room and have to be booked before you check out. There is also a phone number you can call from your room to get the info, but not sure what that number is. Sorry you missed it this time!
As @Wahoohokie said, I have always found it on the table or desk in the room. It has been in the folder that includes resort information. In the middle there has been a section called : Be Our Guest.
For the future, even if you dont see the info anywhere you can dial 8844 from the room phone to check availability, get pricing, and book. Its often a better deal than the other options.
