I think location is a key factor. Being in a (US) state that’s is “open” seems to draw from those states that are “closed”.
I’ve had recent guests from CA, Oregon, upcoming guests from NYC
I just had another inquiry from someone in NYC looking for at least a month in June or thereafter. Before going further I asked her to make sure she was aware of what summer in AZ is like.
“Are you familiar with Scottsdale / Phoenix in the SUMMER? I ask that because it gets pretty damn hot, and I would not want you to commit to something and then ask yourself WTF did we just do. It really is a great place to live except in the dog days of summer.”
