Geezer alert!!!!

Back when I started commuting, we had to use these things called "maps" that were printed on a substance made from murdered trees called "paper". We also had to depend on these things that sit inside our skulls that control us called "brains" We didn't have electronic devices that controlled us.

All kidding aside, yes, I suggest that people do a dry run on a nonwork day so that they can get a feel for the route. Explore a bit and find parallel routes to busy streets if necessary. I often tell people to look at the world with "bike eyes" because far too many look at the world with car eyes. A fast straight route for a car isn't good for bicycling while the opposite is often try for bikes.

I would also suggest that you purchase lights if you are going to ride at night. The majority of bicycling related deaths and injuries happen at night but only a fraction of people ride bicycles at night. And don't just get "be seen lights". Get bright powerful lights...preferably multiple...for the front and rear. This light, for example, cost less than most "be seen" lights and is actually bright enough to see the road even under street lights. If you can see, you'll be seen.

Even entertain the idea of adding one of these lights to your helmet. They are cheap enough and the mobility of a helmet light is very useful.

Good luck.
