Why am I asked to enter my party's names and email addresses? 

When purchasing tickets for multiple guests, you are asked to enter the names and email addresses of your guests in your party.  The intent is that each guest is emailed their own ticket separately and they are added to our email list automatically.   However, for some, this is more of an annoyance than helpful during the check-out process.  You can skip this by simply copying the  ticket buyer's information to each ticket.  

Can I skip entering my party's names and email addresses? 

Yes, you can copy the ticket buyer's information in each of the tickets by using the "copy data from" button. 
Note: You must repeat the "copy data from" operation for each Ticket in your order.
