About not meeting your guests...That outcome depends, mostly on the guest and how you set them up.
I live on site and always try to be there to meet my guests to offer a tour of the cottage, amenities and show where to find extras, and answer any questions. I also try to check in before they leave. I am also clear that if they prefer their privacy, I'm fine with that.
I've had some folks come in very late and leave while I was working outside and missed them completely with no negative effects and others who want to interact and share an evening glass or morning coffee.
I aim to have everything set up with a welcome note so they can be completely private if they want to be...or not.
We have lives as well and have things to do...
