Nothing. Kids should not go to Vegas. There is cigarette smoke EVERYWHERE. Gambling, drinking, advertisement for sex and hookers, photos of escorts, etc. It is NOT a place for kids.
20 years ago Vegas tried to become "Kid Friendly", but the experiment failed miserably. Vegas is no longer (and never really was) meant for kids.
I go there for about 3 months every year, I see families who bring their kids. The kids looked shocked, confused, tired, bored, and not having fun. Neither do the parents. Vegas + Kids = Bad idea. almost 9 years ago
I have a 3-y-old and we went to many places during the day. Check this out: http://www.vegas.com/attractions/kids.html or this http://gocitykids.parentsconnect.com/region/las-vegas-nv-usa
As you see there are ton of activities what you can do and not for babies :)
So no worries.
Some people find good activities, some people do not pay enough attention to it. almost 9 years ago
