Hi,
are the passes personalized on purchase or can one add the name of the person later?
I would like to buy two 1-month passes from the promo today, but the second person isn’t sure she can plan her vacation like I can.
If she can’t make it, I might have to find someone else to use it (or I could use it some time later within 11 months).
Therefore my question:

are passes personalized during checkout?

Thank you for your help.
