For people waiting to buy tickets this morning- it's important to keep calm once your code is accepted and you're into the TM site.
Once you're in, theres is a little clock in the corner counting down how many minutes you have left on each page.
But just relax and make sure your search criteria are correct. You have enough time to make a few attempts at finding the tickets you want.
I was getting freaked out by that little clock yesterday. And after all the stress with the codes, was about to just buy the first (very expensive) tickets that came up. But I pulled myself together- discovered that the search criteria had changed themselves. I repeated the search a few times and found the tickets I wanted for the dates I wanted. No matter what that feckin clock says there is ample time to do searches and check your options.
Keep calm and enjoy-once you're in, the hard part is done!
Best of luck all!
