Do I have to print out the tickets or can I use my phone? And is it the same for parking?

You can use your phone!

Yeah you can use your phone

You can use phone for both, but preferred parking reservation must be made before 5am the day of.

I could not find a way to use my phone for tickets, but I think their app supports mobile tickets.

1 Free parking per two session pass may be for regular ticket too.i think need to print the ticket

They ask you for the print out for prefered parking reservations

You can do both. Parking, I'm not so sure about.
