Yeah I'd love if airbnbs had these. I tend to rent places in mountainy areas with bad cell service. It feels like 90% of the time we arrive bleary-eyed from a long drive, needing to look up a place to get dinner, only to find the welcome packet which has a handwritten password like "FJ#)@Jkfsf2JBbnNVnIOfQPOWre230F(&J%^". Minor annoyance, but a bother all the same. I always type it out in the Notes app first to make it easier to fix typos.
