Sorry no plans for this. There is too much chance of this being open to abuse through the sharing of codes etc and we would risk too many free streams being issued. Also, the way the combination of Planet Ice and TicketCo systems are setup for us means that it’s not really possible to implement.
Our Season tickets are very competitively priced, and you can lend your tickets to a friend in the same category (adult. child, Concession) if you can not attend, and upgrade on the Planet Ice tills.
