A couple years ago we were doing a cross country road trip and needed to stay the night in Las Vegas. It wasn't my first choice, but based on timing/other things in the area we wanted to do (Hoover Dam), Las Vegas was pretty much the best option for a city with lots of hotels.
At the time, my kids were 8, 6, 4, and 2.
We originally booked a room at Excalibur, because I thought my kids might like the theme, but then we changed our mind and booked OFF strip at
The Residence Inn Hughes Center

Pros:
1. Free Breakfast Buffet in the morning! Sure, it wasn't as big and grand as the ones in the strip hotels...but with a family of 6 it would have cost a bundle to eat at one of those!
2. Full kitchen in our room (since we were only there one night, we didn't use it--but could come in handy for an extended stay
3. NO CASINO! This was important to me...as all the strip hotels, you have to walk through the Casino to get anywhere else in the hotel. Of course, kids aren't allowed in the Casino floors, so you have to walk all around the border...and those flashy lights from the slot machine sure look like fun to little ones, who would be asking to stop and look...and of course you can't...just a huge hassle
4. NO SMOKING! All Marriot's are smoke free!
5. The pool was open till 11 pm! When I was looking at hotels on the strip, all of them stated that their pools closed at like 5 or 6 pm! This was in late June! I was shocked they all closed so early. We probably wouldn't even be in our hotel 'till about 6 pm, since we were seeing Hoover Dam during the day...and after a long day in the car my kids would really need a way to burn off energy...
6. Ton's of restuarants right on the same street--PF Changs, Ruth's Chris, Buca di Beppo...yeah, they are just chains you can go to anwhere, but sometimes something "known and familiar" is better when traveling with little kids.
Cons:
1. It was a bit older, probably could have used a refurbishing...nothing dirty or broken or anything...just a little dated looking.
2. Not on the strip...if that's really important to you...It was about a mile from the strip and it was super easy to just drive to one of the strip hotels and park
We didn't really do much on the strip that night. We did take the kids over to the Bellagio to see the water fountain show, and then we had our dinner in Paris at that little Crepe place they have there. We started walking back to our car about an hour after it got dark (can't remember the exact time--we were on vacation!

) and the guys that hand out the escort fliers were out in full force. And yes, they did attempt to pass them to my Dh even though he was obviously with his wife and 4 young kids...
