It's great to find a gift that is unusual and yet a perfect fit for someone you love.
The voucher is good for one ticket on any of the upcoming course dates, as long as there is still a place available for that date. The holder of a voucher can simply email or phone me to book a place on any of the course dates. I will have a record of their name and that will serve as their 'voucher code'.
I will send you a link to a pdf of the voucher which you can forward to them or print to have something physical to give.
