When Photo Ops are at a high demand, sometimes we are able to set aside some to sell at a later date. You must have purchased an admission ticket to this event in order to enter the lottery. One entry per email address. An entry gives you the chance to buy a Photo Op or an Autograph, if they are on sale at the same time.
To access the Photo Op Lotteries, go to the Master Guest List and click on the Celebrity Guest that you are interested in, the Photo op Lottery sign up link will be on their individual Bio page
