You don't need to print them out. There's a QR code that is sent to you with the receipt, just open that and they'll scan it. It's the only ticket you'll need, no need to wait in any ticket lines which can get long.
You can go before they open but yiu wont get in because they are closed. Just get tickets online and have them scan the code. Once they are open, of course.
No cause they're not open yet
Buy the tickets online, print them out. Thats what we did.
