No benefit to renewing early, but renewing an AP is cheaper than buying a new one. Having said that...our passes were set to expire on 2/19/18--I renewed early so that I would get the current promotional rate (Platinum Plus renewal at the Gold renewal price--$505+.) That deal ends on 1/3/18. My new expiration date should be 2/19/19. I entered my 'will call' number into
MDE and it's in as a 12/31/2030 expiration date until I actually activate my pass at Disney World.
