Check out LV Motorcoach resort. It's one of the nicest places we have stayed. Very secure, just a bit off the southern end of the strip. Most of the lots have super nice amenities, ours had a built in grill,surface cooker, gas fireplace, 2 sinks and a 8 or so seats at the outdoor bar. Lots are individually owned , so what you get is not known until you arrive, but all are very nice. I think there were 4 pools on the property so it was a short walk to the nearest pool.
We were there last July.
