Sams Town is a cool place to stay in Vegas if you have kids. For starters they have a wonderful atrium with a water fall that the kids can run around. Also the have a free light show every couple hours in the atrium. I went around Christmas time and this place was decorated so well.
There is a movie theater and a bowling alley on site as well.
As for the gambling if you win, its a great place to gamble and if you lose its a sucky place to gamble. Overall I did OK the weekend I was there. I played mostly Video Poker and won a few bills.
Overall I highly recommend this place because its away from the strip and that is key if you have children. You and your kids will be entertained here.
