what are the beautiful sites and why people enjoy a lot in las vegas?

Las Vegas is a town that never sleeps; therefore the lights never go out. It is a wonderful place to vacation. Following is taken from the Las Vegas Tourism site and I have to agree:
"Las Vegas is the most exciting and entertaining city in the world. Nowhere else can you find a city that has all the travel amenities that only a complete resort destination can offer: luxurious casino hotels, fine dining, wonderful live entertainment and state-of-the art convention and trade show facilities. Las Vegas is a spectacular city, incomparable to any other. Everything that you would expect from a world-class metropolis, and more, is right here for your pleasure.

Las Vegas is a city that has something for everyone. While you are here, make sure to see all the great attractions the city of Las Vegas has to offer. Recognized all over the world, our famous Las Vegas Strip is where tourists can enjoy a walk in the warm desert evening, or take a stroll downtown and view a dazzling light show that spans an entire street, the Fremont Street Experience. You can also get a glimpse of amazing world famous re-creations like erupting volcanoes, the Eiffel Tower and the Sphinx of Egypt in front of the various hotels and casinos.

Las Vegas tourism offers top quality entertainment, including headliner shows and concerts, attractions, shopping and world-renowned resorts. Las Vegas nightlife will keep you up until dawn and art displays, music and museums take you on a journey from the classic to the contemporary. Downtown Las Vegas offers an energetic display of color with a bit of nostalgia and a glimpse of the future.

If you are looking to enjoy the Wild West and our great outdoor recreation, beyond the glamour and glitter of our neon lights, we have plenty to see. There are enchanting panoramas in the Red Rock National Conservation area, Lake Mead National Recreation area and at Mount Charleston. All are only minutes from Las Vegas Strip hotels and casinos. We have helicopter tours of the Grand Canyon, Hoover Dam, and the Las Vegas Strip departing every few minutes.

Las Vegas continuously reinvents itself, so even if you have been to our great city before you will never run out of fun things to do."

When I was a visitor, I always prefered a hotel on he strip. There is so much to see and do there. As a local resident, I prefer the off-strip hotels. I would still recomment the hotels on the strip for you as a first-time visitor. You should not miss any of the sights and sounds that go with the strip. And if you can, take in a show. It is expensive, but well worth it.

I never been to las vegas myself but like you i'm also planning to visit it soon. mostly my knowledge of las vegas mostly came from t.v. and internet also in movies. i want to check every casino hotels and every night spots that there is. I want to watch the shows they are famously known for. and also cruise at night at the very beautiful las vegas strip and watch the water show of the belagio. and try out every possible but legal activities there. what happens in vegas stays in vegas.

Rather than trying to do everything, do some research and pick and choose, flights to Vegas is usually reasonably cheap, hotels rate are great if you don't go on the busy weekend, make it an annual trip, you will enjoy it more than try to pack in all in over a long weekend.

Hotel rates go up when there are some big conventions in Las Vegas. You can check conventions calendor at Las Vegas Visitiors & Convention centre website.
