No doubt Cirque du Soleil is a show not to be missed if you go to Vegas. The special effects, the colors, the choreography and the acrobatics are unforgettable.
From the airport simply take a taxi cab, it is not very expensive and is much quicker. The shuttle buses take forever.
This website, Vegasroom.com is where I have found the best rates for any hotel, much better than booking directly with the hotel.
Best Way To Get Around:
Walking the strip is the best way to experience everything, unfortunately the summer months are unbearably hot.
