Thank you for sharing all of this valuable information. I have my plan in place for our trip at the end of 2017 (fingers crossed that SDFP will still be working). We have 2 DVC room reservations for our family of six, so I was able to add 4 phantoms. I also have 2 magic bands from a trip last year for DH and myself, that are on a second
MDE. So, we will have 6 extra MBs, very straight forward. This morning, DH found our room keys from a trip in 2013 (actually checked in on 12/30/12, for a 7 night stay), that have the mickey icon on the back. We were a family of 5 back then, but we had a split stay, so we were issued double the cards (but have only located some of them so far). I tried to link one of the cards to my second MDE, but I received "sorry we we're not able to process your request at this time...". On the front of these cards is says "DVC Room Only", in the original post it says room keys work, but since these would not link to my account, I am unsure. I don't recall if I had them linked to our tickets when we checked in. Also, since this was pre-MDE, are the keys from the first half of the stay, clones of the keys from the second half of the stay? TIA for any help.
