I do Jen, but it is not totally fair that I jump in becuase I was born adn raised there and my family is there.
However, there are lots of places besides the strip you can go.
Red Rock Canyon is awesome nature. You can do hikes and have lovely picnics out there.
Lake Mead if you like the lake scene and Hoover Dam is interesting.
There are hot springs outside the city (can't remember where they are)
and petting zoo's and Mt Charleston if you need to get into snow
Gosh, it has been so long since I lived there I am not up to speed on everything that can be done there, but they have the past decade, become more family friendy.
