We used our coupon in July, but we didn't know that you had to trade in the coupon at the front of the park before you get your picture. You go to guest services (on the left, directly after the turnstyles), turn in your coupon and they will give you a voucher for your free picture. It is much easier this way, we had to walk back to the front of the park to get the voucher, then trek back to EE to get our free pic. Hope this helps someone.
