If i buy a ticket online, do i have to print it? If not or you guys will be able to know that i buy the tickets. 2. My daughter is 3 years old, can i come with her?

No need to print, if you can pull up the barcode in ticket to show it at ticket countet. In case u dont have access , u can save a offline version of the ticket

Hi Emmanuel - you don't have to print it out. They can read the barcode in the ticket that's emailed to you. As long as you can display the email when you get there, you're fine. You might want to print it out for backup, just in case you have trouble displaying the email when you're on site. As an alternative, you could take a screen shot with your phone - if you have trouble opening the email when you're onsite, you could show them the image - just make sure the barcode shows.

If you don't have access to email while out, print it

I would print my tix just in case and yes you can bring your 3 year old

You do not need to print them. They will send email with barcode which you have present upon arrival.

Yes,,print it to be safe.
