Las Vegas is one of the most popular city in the world. I have had the chance to visit most hotels in Las Vegas three times and I cannot wait to go there again.
The Flamingo Hotel in Las Vegas is located on the famous Strip. This hotel casino exists since 1946. Besides the casino, you can visit a Wildlife Habitat where flamingos are living. As for shows, you can see Toni Braxton, George Wallace, The Second City and Society of Seven with Lani there.
The Caesars Palace in Las Vegas is definitely one of my favorite hotels. I have stayed there during one trip and I must admit that it was simply luxurious. In my opinion, it is the best place in Vegas to shop (in the Forum Shops). There are plenty other things to do at the Caesars. There are bars like Pure, restaurants, and, of course, Cher's show, Bette Midler, The Red Piano, Elton John's show and Jerry Seinfeld among others.
Not far from these two hotels is the Aladdin Hotel Las Vegas. It also has a huge shopping center called the Desert Passage. Lots of shows are hosted there, to have the complete list, I suggest you to visit the official website of the hotel.
Finally, before booking your trip to Las Vegas, I strongly recommend you to look at some Las Vegas deals on the Internet. That way, you might be able to book an hotel at a cheap price.
