You can get hem on the night - but allow yourself a bit of extra time and also have a print out with all your refference numbers to hand - it will make it so much quicker and easier (just wait and see how long it takes the other idiots in the Q who didn't bring theres!)

If you selected "will call" for your ticket purchase, you need to pick them up at the venue box office before the show. Plan on arriving at least 30-60 minutes before the show in case there is a line at the box office. As general information, be sure to have a photo ID and (maybe) the credit card you used for purchase.
which option did you choose? mailed to you? will call? e-ticket? you should probably know this info already.
