is it possible to just walk in and buy a ticket?

You can, but I strongly recommend using the Atom App to buy ahead of time, with the Starpass account there are no fees, and you can select your seats from there. When you arrive you just scan the code on your phone and go in.

Yes, BUT there is no guarantee there will be a seat for you.. The seats are Assigned. Think of it as like a sporting event...sure you can buy tix at the box office, but you might not get the best seat(s)

Yes

Yes you can walk in and buy tickets that's how I do it🙂👍

Yea, just like any theater so long as there are seats still available. You can check online before you walk in and buy.

Yes. But, Sometimes the seasons biggest and most anticipated blockbusters are all booked up in advance on apps such as atom etc. So better to book the biggest blockbusters a week or two in advance. I hope it helped.
