The important part of OP's message is the title. I'm assuming the OP got the Magic Your Way package that included Memory Maker for free. I'm in the same boat, I booked the "MYW package with Memory Maker" months ago. My magic bands will be shipping any minute and in
MDE, there is no mention of Memory Maker, other than the standard option to buy it.
I've asked 3 separate CM's how it's going to work and I got 3 different answers. One said that a card will come in the mail that I will use to link it to the account. Once said that I will get the Memory Maker code upon check-in at the hotel and I will use that to link it to my account. One said I don't have to do anything and it will automatically work.
Anyone have any definite answers?
