It's a tour so I guess you need to pick up a date and a time, but call the office
Call the office.
I went in early December 2020 and I bought my ticket online and chose the date I wanted to go. When I went to enter they just asked for my name and had my ticket purchase on record for that day. No contact needed. :)
Yes, you pick the date & time. I don't recall printing anything; I think I just showed the receipt on my phone.
Pick a date, based upon availability, which will be listed online via their website. Pay for tickets online and print receipt for your records. They will have your name on their list.
