There are many things to do in Vegas from shopping, watching shows, gambling, and visiting amusement parks.Quick Tips: I don't recommend spending a lot of money on a hotel room as I find after several trips that I am never in it except to sleep, shower, and change clothes.
I also would not rent a car unless you want to go to places like the Grand Canyon or Hoover Dam. The shuttles are great to get to the hotels. The trams can get you around to different casinos without too much walking, and if you want to go downtown, take a cab for about .00.Best Way To Get Around: Walking is the quickest way to get around on the strip.
To go to Fremont St. - you will need to take a cab.
