My wife is thinking to put a plastic vapor barrier over the dirt floor and to cover with rubber mats? 

@Paul SandhuYou could get them plastic pillow cases, so when they slobber in there sleep, they won't get tobacco stains on their pillows.

Interior: new concrete garage floor, refurbished wood floors, paint, gutted bathrooms/kitchen, added bathroom shower, doubled all BR closet space, removed kitchen walls for open concept w/ dining/living rooms, added cabinets, new appliances, tile floor/back splash, installed dining room french doors onto a new deck w/ refurbished original stone patio.

Renovations included but weren't limited to: Point-up & sand walls, new paint, new floors in kitchen, new cabinets, new appliances, added washer and dryer, completely remodeled bathroom, bathroom door replace with a barn door, fixed pipes and installed portions of new piping in bathroom, recess lights added in living room, remodeled the back "patio" into living space (could be used for an office or den), steps in the back were fixed, new doors and locks throughout, new thermostat installed.. etc What was the outcome?

The in-person meetup will be outside on a large patio so people can spread out, we have plenty of hand sanitizer, and we're recommending that everyone wears masks.

The modern composite materials IMO are 100% recycled plastic and there's little wood in it.

Closing outdoors on patios?

It definitely has a plastic look to it no matter how well you install it.
