During a week-long business trip, I was fortunate enough to stay at this beautiful property. However... on a Saturday night after a LONG day of travel, I was up until the beach concert/party was over. I had to listen to a constant thud from the bass vibrate throughout my room. The front desk staff was very polite, but since the hotel was sold out, all they could do until the next day as move to me Mandalay Bay. (If you know the property, this is not something you want to do later at night.)
So... if you are visiting over a weekend and are not there to party, be sure to ask for a room that faces the outside, NOT the Mandalay Bay beach.
Otherwise, everything is impeccable.
