The monorail was my best friend while in Vegas. It was only $12 for a 24 hour pass, and I got one every single day I was there, and it was well worth it. Instead of walking the entire strip you can just get off at whichever stop you want and explore the casinos/area. I only took a cab once on my trip and it was more expensive for one cab ride than it was for the monorail! If you want to see the whole strip and don't want to walk the entire thing, the monorail is the way to go! I loved it. Plus you can bring your drinks on it with you, what could be better?
