While on vacation in Las Vegas, my family stayed at two different hotels (due to rates/availability). The Orleans was by far my favorite. It offered so much in entertainment, which was a huge plus for someone who doesn't gamble.
Note: If you have allergies, breathing problems, or sensitivity to smoke (me), I also recommend this hotel. I was practically glued to my inhaler while visiting the casinos on the strip, but I didn't need it at The Orleans.
