In answer to your question...

Provided you let us know a minimum of five working days before the event we will move you to another event free of charge or refund you less a £5 per ticket administration charge. Between 1 and 5 working days before an event we will move you to another event for a £10 per ticket administration fee. If you let us know less than 24 hours before an event you can send a friend of the same sex in your place for no additional charge. Just call us on the number shown on the relevant event page. We cannot move you to another event with less than 24 hours notice. However do please let us know if you are unable to attend, for whatever reason, as imbalanced numbers spoil our events for other people attending.
