Did a search and didn't see anyone talking about the new AP cards.
I renewed my annual pass yesterday and noticed my new card is different. The CM at Guest Services went into detail:
1. The new cards no longer have the expiration date on them.
2. The cards don't have the type on it (ex. Deluxe printed on it)
3. The Disney "D" indicates to the cashier at stores and restaurants that the passholder is a premium passholder and should apply the premium AP discount.
In addition, when you renew your AP, the new card DOES NOT activate until the day after your old AP card expires so depending on when you renew it, you'll still use your old card until the day after your expiration date. Also, the new card stays with you since they'll no longer issue new cards to renewals (the exception is if your card wears out.) next time you renew, you'll still have the card.
If this was posted before, I apologize and the mods can merge this to the appropriate thread.
