We are thinking of a 4 night trip to LV. This would be our 1st time to LV and have narrowed our choices in hotels down to Encore, Caesars Palace, Signature at MGM, or New York New York. Out of these four where would you pick and why? We would like to be close to mid strip and we're not really fancy people but do like a nice room when we go off. Any help would be greatly appreciated. Also, we would like to go to the Hoover Dam. Should we rent a car for the entire time or just for the day? Are there places on the strip to rent a car for the day?
