You are able to upgrade your Membership at any time throughout your annual membership period with AT2. You'll simply need to pay the difference in package cost. 


For example, if you join AT2 on the Standard Adult Membership for $119 and then upgrade three months later to the Multimedia Adult Membership for $169, you simply need to pay the extra $50 difference in package cost. Your annual membership period stays the same, you are simply upgrading your membership. 


You are not able to downgrade your Membership on AT2.
