Having just 1 adult guest for a few days has worked out well over the years.

Our home can only have 1 guest to sleep overnight. We have a small place. It's a condo. ANd guest must sleep on the floor on an air mattress. Yes, floor is carpeted though.

I grew up in a home where all family members never walked around at home in their outdoor shoes. it's either slippers, socks or barefeet.

And that's how it is at our home here.

So far, it's worked out such that guests I've had didn't stay long enough, that they were allowed to cook for themselves. I encourage them to help themselves from the fridge, etc.

We've had people take showers down in our common fitness workout area. Makes sense when it's more than 1 person..and you encourage them to use the common swimming pool and whirlpool.
