Panoramic views lovers have a wide range of choices: helicopter tours to the Grand Canyon, baloon rides, off the road trips in Nevada Desert. For the most atheletic spirits, canyoning or rafting on Colorado River are the things to try.

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.  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 Brian Hoffman's Remembering Red A Tribute to Red Skelton and  '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 the late night crowd, the Sapphire Comedy Hour  has an outstanding show with national headlining touring comedians with film and television credits and world-renowned magic and burlesque acts.

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