We have older family that we see as risks and all see that going back to school adds more risk. We have two different rules based on the parents risk tolerance:
1) My mom is more open. There we can go into house, but all sit in the same seats each time and use a bathroom where she never goes (maid cleans). We also wash hands at our house, hand sanitizer in the car and again when we get there. No hugging or touching.
2) My wife's parents are less risky. There, no one goes into either house. We meet on driveways in our own chairs (or at our pool ... they do swim with our kids, but don't touch). We keep socially distanced and stay away if signs of sickness.

Maybe that will give you some ideas where you can still see them. Good luck!
