Please don't worry. Firstly, please check your junk or spam folders in your inbox as sometimes our e-mails can end up in the wrong folders.
Secondly, when the booking was completed online, it should have provided you with your booking reference number. If you have this, along with the card you made payment with and photographic ID the team onsite will be able to locate your order and issue the tickets upon arrival.
If unfortunately you don't have the reference number, then don't worry. If you complete one of our contact us forms here and a member of the team can confirm your order and resend the e-mail confirmation.
