Do I have to print the tickets I got emailed? Or can I just have the etix page with them on my phone?

Either way, just be prepared with tickets on your phone, screenshot them and make sure to have brightness up to ensure smooth entrance.

Honestly, I would try to print them. It seems to make things go smoother and quicker if you just have something to hand to the ticket takers.

If the etix has a barcode they can scan it on phone
