Place to stay in Las vegas

[Thumpt]

Hi all i am planning a trip to the US in May and part of the trip i will be spending about a week in Vegas. Can anyone reccommend a place to stay that has somethiung for the kids and the parents. The more i research Hotels the more they seem the same. I will be doing a helicopter flight over the Grand canyon, but have nothing else definately booked yet. Looking for a few tips from the locals or people who visit the area .

Will be doing a cruise out of Miami and spend some time in San Francisco aswell. Any other must do things, let me know.
