another bounceback question

[tinkfan05]

I am going to WDW in Oct. of this year, and then again in May of 2009. We already have a deposit on our package for May. My question is, is it possible that I could get a bounceback when I go this Oct for next May? And if so, what do you usually get with the bounceback? Is it a discount? Here's hoping to make my May trip less expensive!
