We make it in less than 4 by car no thanks
Even a relatively "short" 3-hour trip by car on a congested interstate can be a miserable trip that leaves you feeling all worn-out when you finally arrive at your destination.
Even if it takes a couple hours longer, I'd much rather relax and have a good time on the train. Let somebody else worry about the highway traffic. It makes for a much more pleasurable visit to Vegas!
I’d rather get there at the time of my choosing, able to make any side trips I want, and have my car with me at my destination.
I had the pleasure several years ago of trying to get back to the coast by traveling the interstate between vegas and LA on a Sunday. It was worse than your standard rush hour traffic! Stop and go from Vegas to Barstow (where I got off to head towards Bakersfield). If there is that much traffic between the two locations - a train would be my way of travel -less stress and ready for action.
I prefer to “drive” than take a train..
