They will have unique access to the Palácio Real de Madrid without having to wait in queues or go to the ticket office, with the tickets they can go directly to the access lathe.
Travelers will receive “no-wait” tickets for the museum via e-mail. Tickets will be sent 24 hours in advance (relative to the time of reservation). This is a no-wait entrance, but the security check is mandatory and travelers may have to wait to pass it.
