? about Disney Packages

[A.Mickey]

Alright so my husband and I were thinking of doing the 4/3 package without park tickets so we would have the one day base ticket on our room ressie. But I know you can apply this to an annual pass. How does that work?? Will it give us 75 dollars off each AP then? Or can I keep it and use it the following year after our AP expires. I know you guys are quick and helpful with questions .
