I am wondering the same thing. I have made all my ADRs online and there are ALOT of them (DxDDP for 7 nights). Yesterday I was on the phone trying to get a Fantasmic package and the CM told me I needed to link all my ADRs to my resort reservation for the dining package to 'work'. That seems contrary to what alot of DISers say from experience (just to tell the waiter you're on the
DDP and make sure the receipt takes them off correctly).
So do I really need to 'link' them? I didn't do it yesterday because I didn't have the confirmation numbers handy. I don't really want to call up with all of them if I don't need to. Plus, I imagine I'll continue making lots of changes between now and my trip in September!
