We used the "Bounce Back" Tickets a couple of years ago when we did a short visit to see the Christmas decorations! They worked out fine!
You buy a one day pass, and if you want to buy a second and/or third day, you get a discount on the 2nd and 3rd day (off the price of the one day ticket) I think it was about $130. However, these are one day park tickets that do not allow park hopping. This was fine with us - since we were there for a four day weekend.
