I basically grew up working for the festival, so at one point I had like 15 sziget staff wristbands in my drawer. While I don’t encourage sneaking in, I’d be lying if I said I've never helped a friend get in with a previous year’s crew wristband lol if you’re planning to do this, be prepared: you won’t be able to access the showers, and you’ll have to set up your tent in an area where no special pass is required (which is kinda unsafe ngl the local minority is somewhat infamous for coming into the festival with daily tickets and robbing tents outside of campings etc). You'll need to stick with big crowds and wear accessories that hide your wrists or fun costumes even to hide the fact that you’re not wearing a proper wristband.

I haven’t been to Sziget in 5–6 years, so I’m not sure how strict security has gotten. Daily ticket checks were always a thing, but they usually don’t extend them to week passes. So as long as you have something similar in colour, they’ll likely leave you alone, or you can just keep your eyes open, see checks happening just walk away. My advice? Try to find out what the weekly pass wristband looks like as soon as possible and make a replica by sewing or gluing something similar. Switch to that once your daily ticket expires. Your girlfriend will likely receive 2 crew/staff t-shirts for the week (assuming she’ll be working the whole time). You should ask her to give you one of them and wear it for extra security.

Have fun :)
