Unfortunately...the ones they offer with the L/S package are only to be used while you are there.
You might be better off to look into booking the land and cruise portions separately. This will give more flexibility in which hotel you want to stay in, how long you want to stay at WDW and which ticket media you want to purchase. Also note that food is not included in the L/S package for the land portion.
We have found if you book the two parts separately it costs less and you can still add on DCL transfers if you want. Good luck!!
