All the information regarding when and how to register your date for the Debs.
Guests do not need to worry about registering plus 1's. The Debs is many months away and we understand guests may not know who they want to bring.
Concentrate on getting yourself registered for your Debs and don't worry about anyone else for the time being.
Plus 1's will get registered via ticket purchases whether they purchase their own ticket and fill in their details or you do it for them.
