Can we pay when we get there or we have to order the tickets off line ?

If the ticket line is short, you can save the online fees and pay there. If the lines are long you can just do it on your phone. You do not have to have the ticket printed out like it says online. The speed pass ticket booth is at the top of the hill attached to the main haunt...the regular tickets are at the bottom of the hill on the left side of that building. Also, buying there you can n use the coupons from subway for extra money off. Either way n it's well worth it.

Either one. But if you buy there, you have to wait in another line.

You would be better off to get tickets ahead so you can avoid two lines, but you can buy there.

You can pay on location
