Families with kids - Casino headaches
Families with kids should know one thing. Kids they're not allowed in casinos at all. Because most hotels are laid out so that you frequently have to walk through their casinos, you can see how this becomes a headache. Some casino hotels will not allow the children of nonguests on the premises after 6pm and this policy is seriously enforced.
Flyers & Kids - They don't call it Sin City for nothing!
Note also that the Las Vegas Strip is often peppered with people distributing fliers and other information about decidedly adult entertainment options in the city. Sex is everywhere. Just walking down the Strip might give your kids an eyeful of items that you might prefer they avoid. (They don't call it Sin City for nothing!)
Discount for children staying in your room
Although still an option at most smaller chain hotels and motels, the major casino-hotels on the Strip offer no discount for children staying in your room, so you may have to pay an additional fee (anywhere from $10-$40 per person per night) to have them bunk with you. You'll definitely want to book a place with a pool. Some hotels also have enormous video arcades and other diversions.
