Do you have to print your tickets? Can the pdf of the ticket just be shown at the ticket counter?

Only thing I can say is call them... I seen some machine that was outside the ticket booth but it looked closed or out of order.

I'm not sure never did it

I don't know. I've never heard any conversation about it. However if it's offered online I would guess that day will accept it.

I am not sure as a am a annual pass holder. I have not used the ticket window in years
