Stay away from the roach hotel. You will be better off sleeping in your rzr. Primm is one disgusting place. In fact just keep going until you get to Vegas, at least you will see some good looking people there, even if it is made of plastic. Lol.
Just an FYI if you have to many cars traveling together the blm can ticket you for and organized ride without a permit. I heard of this happening very recently on the same run.
