I was actually surprised at how quickly the renewal came this year. I think I got the cards within a week to 10 days of mailing in the form. Last year, it took 2-3 weeks. As long as your renewal is postmarked before your expiration date, they'll still process it. If you have an upcoming visit and don't get your AP back in time, you can go to guest services and they will issue you tickets to get in the parks, as long as it's not a blackout day. That's what we had to do last year since it took so long to get them back.
