Print it. It's cheaper and incase you buy at the gate watch out for the guys who sell you the ticket. They will. Make you waste money. It's so huge you won't cover everything less you go early so get just the tickets with no shows and then carry cash in case for example you want to feed the girrafe etc. You will save money. Just a means of making you pay for something you won't even get to.
Their website has all of this information plus discounted rates if you buy online and print at home
Look for a good deal on Groupon.com
