In general, any ticket purchased outside of a package is completely separate. You should be immediately charged for it and it will be sent to you as a separate transaction, just as if you had no package at all. You can opt for the will call option and save the $3 if you'd like.
But you will still be able to have it put on your resort ID when you arrive. Just present the separate ticket to them and they will encode it onto your ID. They couldn't do that in the recent past but they can now.
