I always just thought the keycard was more about keeping vagrants out, than guests and their invited friends.I wonder if the type of hotel and the fact that they require a key has a correlation. I’ve been told years ago that Marriott was very anti SW but I’ve found some of their hotels don’t require a key for the elevator
I don't pay attention to what places have keycards, I generally just ask if they can meet me outside, so we can walk in together. On the very rare occurrence they don't meet me outside, I do think to ask if a keycard is needed, and in some places the keycard system was only in place at night, not threwout the day. (Why I think it has more to do with a homeless issue, than a SP issue, but Icould be wrong.)
