Yeah, they are a real pain!
For the spouse pass, when I look in
MDE, under 'Tickets & Passes', my MEP, 3 GP's and my husband's spouse pass are all listed there...spouse pass is listed as "PARTNER*******" (**'s in place of our last name). In the "Assigned To" column there, it says the same thing "PARTNER******" and then it's designated as non-transferrable, just like our MEP and GP's. So, it's not linked in MDE to a specific identity (in this case my husband) that you would be able to choose as a person on the room reservation...if that makes sense? Even though we all know that pass is only for one specific person and their name is printed on the back, in MDE it's not really recognized as being linked to a person...it's just treated like the GP's in that sense. It really makes no sense to me...unless mine is just messed up for some reason? Do other's SPs look differently in MDE?
I also don't understand why if all of the passes - MEP, GP's and Spouse pass - are listed under my identity in MDE when I look in the Magic Bands & Cards area and the Tickets & Passes area, why it wouldn't automatically then recognize all of them as resort guests if I am a resort guest during a stay.
