Yes all Disney hotel guests are eligible. The info is in the booklet they give you when you check in. Also, you can also call the Bounceback X8844, extension 8844 from your hotel room phone.
You must call up until midnight of your check out date (the full phone # is on the pamphlet, I often book my Bounceback when I’m at MCO waiting for my flight home.

200$ cc deposit to book it. (Which is refundable I believe if you cancel)
