We spent a week at the Mandarin Oriental over Valentines. We liked the room so much on the first night, that we upgraded to a Premier Room for the rest of our stay. In my opinion it’s not worth the upgrade - stick with the standard room, unless you need extra space. Overall the hotel is fantastic, great quality throughout, the only minor negative was having to change lifts to get to your room (same for standard and premier). The restaurant is a la carte and serves an absolutely delicious breakfast, but it did get a bit busy over the weekend.
All rooms are non-smoking and of course there is no casino. But don’t worry, the hotel is walking distance to the strip and all the action. The Aria Casino is a short 5 mins walk.More
