Next time you think about wanting to stop at Primm on your way to Vegas, don't! Just keep driving..... and when you get to Vegas...... keep driving on I-15 and go to these outlets. It's SO much better than Primm -- by a long shot.
The stores have more merchandise and there are better stores. Plus, an outdoor mall is more appealing to me than an indoor one. They offer valet parking for $5, but there is a parking structure with more than enough parking available so you can opt to do that if you don't want to spend $5.
