3) How do I update my personal details in the Customer Account?

You can update your title, gender, name, address and contact number details by clicking on the ‘Update Personal Details’ link on the Customer Account homepage. If you update your name in the customer account, this will not update your booking. 

Unfortunately, you're not able to update the email address linked with your Customer Account; if you wish to have an account with a different email address, you will have to create a new account.
