Walmart Overnight Camping in Seidel's Blog A blog by Seidel Posted November 4, 2013 · Report reply Hi folks. I am a Security Officer Supertendent, in the Southern New Mexico area. I have 9 Walmarts in the area. I instruct all my officers to park, advise of the area, and make for a happy stay. Most walmarts, want you to limit your stay to a 2 day max. If you happen to stop in Las Cruces, I can guarntee you an enjoyable stay. My officers are instructed to inform you best places for fuel, propane, and fine dining .Have a great stay, and lets all enjoy. Thanks for this post. I am a native New Mexican and appreciate this. We are planning a trip to the Southwest this spring and I would love to stop in Las Cruces as this is where my Dad and Uncle grew up. I definitely look forward to staying at the Las Cruces Walmart. Thanks for the awesome New Mexican hospitality!
