Pictured here is the now ancient Hilton and a new behemoth looming next door, just across the monorail track.
If you want to get up and down the strip fast and see the many faces of the hotel industry, jump on the monorail and tour all of the amazing structures that dot Las Vegas Boulevard. Each station gives you access to a half-dozen of the big hotels. Very fun and all for a 12 dollar day pass. Compare that to taxis in Vegas and you are saving a lot of money.
