There are lots of other options for all ages in Vegas. Must sees are the Ethel M Chocolate Factory, M & M World, Gameworks (great place for kids and adults), and the Coca Cola factory.

There is also the Fashion Show Mall to walk around.  And, the Deuce will take you south of the Strip to the new Town Square Mall or the Belks Las Vegas Outlet Mall south of McCarron Airport.

The Deuce will also take you to 'Old Las Vegas', north of the strip. There you will find 'The Fremont Street Experience,' an overhead canopy of lights that will display to music plus a 4-block-long block party with live professional-quality musical performances and other free entertainment. Evenings only of course.

Also it is a lot of fun to just tour the hotels along the strip - but make sure to wear comfortable shoes! Caesar's Palace is a HUGE hotel and has a very cool shopping mall inside with the ceiling even patterned to look like you are outside (blue sky and fluffy clouds). Be careful going in here though as it is easy to get lost. You might also want to check out The Grand Canal Shoppes at the Venetian and while there don't forget Madame Tussauds. 

Also there are several hotels along the strip for the thrill seekers out there - the Stratosphere with 3 rides at the top of the Tower, one that shoots you up in the air, one that works like a Teeter Totter and dangles you over the edge and one that hangs you over the edge and then spins you around at 65 MPH. Also the New York, NY has an awesome roller coaster as does Circus Circus and the Sahara.  There are also free performances of circus acts throughout the day at Circus Circus.

There are also plenty of shows for both adults and kids- Cirque du Soleil, Blue Man Group, several magic shows... and don't forget Excalibur's Tournament of Kings dinner shows.  One of the only comedy shows in Las Vegas that kids are allowed to attend is 'Larry G Jones' Superstar Voices in Concert' which offers song parodies and singing imitations of Las Vegas' top headliners and shows. If you're into art, both the Venetian and the Bellagio have excellent galleries. 

For classic car lovers, there's the Classic Car Museum at the Imperial Palace (almost all the cars are for sale) and the classic car exhibit inside the Caesars Palace Forum Shops near the Fall of Atlantis Animatron Show.

There are also tons of great Las Vegas tours available to you, both directly in Las Vegas or in the surrounding Las Vegas Greater Area. Fly high above the Strip on a Las Vegas Strip Helicopter Tour. Soar below the South Rim of the Grand Canyon on a Grand Canyon South Rim Helicopter Tour. Explore the dude ranches of the outskirts of Las Vegas on the Grand Canyon Ultimate Helicopter and Ranch Adventure.
