I went there to validate my Canadian tickets (20% discount). It was weird. They had a line outside the building just so you could put your name on the list. Then you had to wait 30 minutes until they texted you to say you could come inside the building. Once inside the building, you had to wait for your name to be called. It was a weird system but I didn't mind... I just went to one of the local restaurants and enjoyed a drink of alcohol.
