We have two reservations linked to one account in MDE. We have purchased the memory maker. Can all of us on both reservations use the memory maker? I personally am on the second room with a 5 day base pass. I am wanting to upgrade to an AP. Will I get credit for the memory maker towards my purchase of the AP? Also on our arrival day we are going to Disney Springs. Where in DS can I upgrade to the AP? I want to be able to use the AP discounts that night. TIA!
