The Mickey mail in this case would be the package from Disney Destinations that has everything about/for the trip in a booklet form. It will also have the souvenir luggage tags. The booklet has reservation details, vouchers for various discounts & freebies. Also a $15 off voucher for Planet Hollywood at DTD. Everything is detailed & bar coded Magic Bands will indeed be at the desk waiting for CDNs at check in. We also booked with a TA (for the first time this time) and our Magical Express package arrived today. 29 days out. I would give your TA a call to be sure he/she actually booked the ME for you, it is done separately (as per my TA)
