Most of the time, I get by without a car. I get there Sunday and will stay at the Hilton. I am teaching a class not far from there and arranged for a ride. The Hilton is off the ‘strip’, but it has many restaurants and other stores. You could easily end up not leaving the hotel. I have been to Las Vegas many times and do not have a desire to see the other sights, but they are worth seeing. On the major boulevard, called the ‘Strip’, the hotels have attractions that are worth seeing. For example TRESSURE ISLAND has a body of water with wooden ships and pirates. Every hour or so, they do a skit. When I have needed to go to a special store, like Best Buy, I found it easy to get a taxi. A car would be nice and parking is generally free at other hotels. It depends upon what you want to do and see.
By the way, I live in Frisco.
