Just double checking 
We are purchasing 7 day wp&m park hoppers for our August DW trip. We will be staying at a DVC resort and plan to pre-purchase the dining plan. On our last day we plan to upgrade to premium annual passes.
Question 1: The premium annual pass is good at both DL and DW with no blackouts correct?
Question 2: Will us having the dining plan affect buying and using an AP on our last day?
Question 3: These passes are good for 1 year from the date of our first ticket use?
We live in CA and have had deluxe annual passes but never premium. I'm hoping to get 2 DW trips and 3 DL trips out of them so I think it's well worth the cost
