I agree with Colleen, snow should be expected. I leave shovels by all of my doors and a notes inside explaining how to use and I mention in my welcome note that we may or may not be able to shovel but they are welcome to, everyone has been able to understand that we don't control the weather. I have grills outside, no one has used during a snowstorm. Most people enjoy the snow using show shoes, sleds, skis, etc otherwise they wouldn't be visiting in the winter. I don't have a solution , but I definitely know, I would not want to host that guest. So sorry you had to deal with that, you have patience.
