Nose around the non-strip hotels...usually if you are staying for over a week you can get a fairly good deal. I suggest taking at least a day to explore the strip, even though you may have absolutely no interest in gambling (which I don't lol). The casinos have a wide variety of things to do, plus the shopping is spectacular...especailly in Ceasars Palace (The cheesecake factory is a must! )

I live in Reno, but Ive been to vegas many times and always find something new/interesting to do each time I go.
