The only thing holding the Aria back from a 5th star in my review is the price.
The rooms are gorgeous, the shops and restaurants are top notch, and the Casino level smells like vanilla! Aside from a lack of casual dining areas, which causes the existing casual dining areas to get packed at meal times, I loved our stay here.
The casino is very conemporary and clean. The art throughout the hotel is great, and the surrounding venues are very nice to explore. Stayed during Chinese New Year and loved how it was decked out for Year of the Metal Rabbit!
