The ticket office will be open from 10am until 6pm on Friday, before opening on the Saturday morning and also most of Monday. However, semi-final tickets won't be available in the few hours ahead of the Hibs game, but will be available afterwards.
From Tuesday, April 14 the tickets will be available to everyone, not just season ticket holders.
Ticket prices range from £15 for adults in the family section to £25 in the most expensive sections.
