Like everyone above has said the paperwork lists the guests and what stuff gets loaded on to each person's room key and you get that at the front desk, when you get there.
I was a bit disappointed with my packet though. The information book in it was already out dated and really nothing new or exciting in it. The Diamond parking pass has blackout dates for MK parking for while we are going to be there so it is not much help either.
There was nothing in the packet about the dining plan. When we booked, TA had given us a zeroxed copy of the list of places and that is all the information we got on the meal plan.
I guess the luggage tags are nice with the castle on them but all i all the packet was weak.
The only bonus I could find was the single admission ticket to the lounge in Tomorrowland good for a single beverage per person. We have never been to the lounge before so I guess this will be nice.
We are still waiting for our ME luggage tickets.
