ticket question

[Disneynutbsv]

I'm purchasing my tickets directly with my package from wdw, but I do have 2 plus passes left over from a previous trip, can I just bring them and then add them to my room pass? The tickets themselves aren't in that great a shape since being carried around so much, and the less I have to carry around the better, so I was just wondering

You will not be able to do this. Disney cannot combine multiple tickets (in your case an old one and a new one) onto any ticket media including resort ID's. Even if you had theme park days left on it and upgraded or applied the dollar value of the ticket to a new one, you would lose the unused plus options associated with the old ticket. You will have to use you old ticket as is.
