No need to print. Keep the email on phone, show it to them upon arrival. They will scan it.
I was able to show them the tickets from my phone for redemption. I would try calling them if anything to see about pick up.
As long as you have electronic copy on your phone to show them, you're disco. If thats not good enough, just call them up.
You shouldn't have a problem
You should be able to show them that you purchased the tickets they should let you in.
If you were sent an email confirmation, you can show them that when you arrive. I'm pretty sure they will have you on file.
