It is not necessary to reserve your visit. You can use your tickets on an opening day of your choice within the validity period of your ticket, without reservation. Date tickets purchased online are only valid on the date indicated on the ticket.
The expiry date is clearly stated on all tickets. If it is still not clear until when your ticket is valid, you can send an e-mail with a clear photo/scan of your tickets to info@plopsa.be. We will then be happy to check the validity of your tickets.
Tickets by date are valid only on the date indicated on the ticket.
