We are are family of six, plus my sister, her husband, and their dog. We don't gamble, but we met in Vegas over New Years due to the decent weather, places to hike, and dog-friendly parks. It was great! The property manager, Linda, was very available and helpful.
The house is big and we used all the space. The beds were comfortable and the kitchen had enough supplies to cook for eight people every day. (Bring Tupperware and forks, to make it a bit easier.) Grocery store is less than five minutes away.
Nearby attractions: Red Rock Canyon is beautiful, and all the hikes are great, especially Calico Tanks, Ice Box Canyon, and Pine Creek Canyon. You need an annual pass and a $2 reservation to get into the main part of the park, so look this up ahead of time. Valley of Fire is incredible. Gorgeous hikes there. Definitely worth the drive. Hoover Dam is also amazing, and there are hikes around it. Our kids loved the Percy Jackson tie-in. For limestone rock-climbing Gun Box Canyon was fun, but you need someone who can lead bolted routes, and the easiest is around 5.6. (Calico Basin has lots of bouldering, but the sandstone was wet.)
The parks in town are also terrific and dog-friendly. Near the house: Spring Valley Community Park, Desert Breeze Park. Three mile loop for running/walking in Cottonwood Canyon Park. Huge park near the airport Sunset Park. All allow dogs!
Other attractions with nice walks/historic info: Spring Mountain Ranch, Springs Preserve and Nevada State Museum.
We went to the strip one night to check it out. Parked at the Ballagio (under 60 min is free). It was cool to see but not our scene.
The backyard of the house and pool area are very nice, and I'm sure we would have loved hanging out back there in another season. We were sad to leave this house where we had a great time together!
