If you cancel your subscription during a cycle you paid for: You will not be charged for the following pay cycle, or any other pay cycle henceforth. You will have access to the benefits of your subscription for the remainder of the cycle you already paid for. Your account will no longer have access to subscription benefits once the cycle you paid for ends.
 
This means that you will lose:
  • Access to Light Fury (however she will remain on Berk & keep all her progress)
  • The golden Mystery Pack
  • The 4th exploration bag
  • Early access to events
  • Extra hangar space
  • Daily runes
 
 
If you did max out your hangar before, you would have to free some space in order to be able to train and feed your dragons again.
