Do we have to pre order our tickets or can we get them at the window

Get online ahead of time to reserve seats, otherwise get at window

Your choice

You can do both. I do believe returns must be done at the window in person.

Either way is fine

You can do both. Buy at window or pre order. I prefer to buy online only to insure that there are good seats left.

If order it's for that day. I think you have to use that day. If know want movie want to see that day you buy it at window. I usely buy my ticket at window.
