Modifying an Order
Based on extensive market research (ok, we asked two people), we know that the most common order is for two adult tickets. To make life easy for the typical user, we assume that quantity whenever tickets are ordered
Of course, many users will need different ticket quantities, so we make it easy to modify an order, too. All the user has to do is select another quantity from the adult or child ticket drop-down list.
When this happens, we immediately update the total charge shown on the screen.
