call disney reservations, and then they'll give you the ME number. I am 12 days out and while I received my package info around that 25day mark, i did not receive ME info. Disney has it recorded that i added ME info on 9/21 and that it was shipped out on 9/29. when i called ME they had record of the reservation but not my flight info. Had to give them my flight info and they are sending my info.
