I attended a pediatric conference and my family tag along with me. I have a 6 and 5 years old girls that I am a little bit nervous that "casino atmosphere" will not be a good place for them. Surprisingly it was a very nice and kids' friendly hotel. My kids were greeted with a warm welcome note made with chocolates in a plate and with their names also in the bath tub.They were very excited and loved the area and my 5 years old girl told me , "Mom I think I want to stay in these hotel for 3 years". ..
I highly recommend to travellers with kids. I am going to Las Vegas for another medical conference this year which will be held in a different hotel but we'll still be staying at four seasons' hotel.
