How do you get from Cosmo to Aria without going back out onto the Strip? When I did my first speed Casino Walk, I went back out to LVBlvd and up Aria Place. But a friend did it, and he claims he went out the back of Cosmo and right up to Aria. I tried it two years ago and just ended up amongst the traffic for the parking garage and really no sidewalks or crosswalks were to be found. At that point I just gave up. Looking to break his time of 2:48 and don't want to get lost again.
