We are frequent travelers to Las Vegas and one of our complaints when we leave is that we didn't see enough of the "heart" of Las Vegas....too much moving around to outskirt casinos, etc. So, this year, we've decided to leave the rental car and do our traveling on foot. However, that leaves us with the hurdle of getting from the airport to downtown, then downtown to ballys, then ballys to downtown. These rides we figured on getting a cab because the fear of the 2 hour drive on a bus stopping at every casino does not appeal to us. With that said, how much can we expect to pay for cab fares? How do we identify the "long haul"?
