Great service here. I stayed here part of CES week, where I stayed at Bellagio, Aria, and Mirage. Out of those, Bellagio was my favorite, then Mirage, then Aria in dead last. The only thing I liked about Aria was how pretty the architecture is. But Mirage has nicer rooms, better towels, and I love the tropical plants in the dome that make it feel like Hawaii.
Mirage also has some pretty good gambling, according to my friends who gamble (I don't). And the Cravings buffet is a good deal for the price.
