The main benefit of the second gold discount card is it shows you that your pass expires one day earlier than you expected.

My first AP card had an expiration of 8/21/14 written on it by the CM who handed it to me. The new card says 8/20/14. Sigh. But a reminder: If you buy a new AP online you get sent a voucher that must be activated. You can link the ticket in
MDE using the reservation #, and make FP+ in advance, but you will not get a MB order in the system until after your first visit and activation of the voucher. This was too much to bear for my daughter so we had to buy her a MB after we activated her pass yesterday even though she will get one in 2 months or so.
