Yes we did pick up our bands, etc at the front desk of AoA back on Dec 28. They really didn't have any details of the CDN discount and said our tickets were attached to our bands, however we did arrive very late so not sure the A team was working then.... The next morning at our first park (Animal Kingdom), our bands would not work for entrance until we went into the Customer Service office and they got us set up properly. So no the tickets are not set up on the Bands but we also were not given specific "exchange certificates" either. They just sorted it out in Customer Service and only asked for Canadian residency for one of the 6 in our party (we all had proof). After a 5 minute delay, we were good to go....
