We enjoyed our stay at Aria Hotel & Casino. The buffet was decent and they have an overpriced Starbucks where they charge $6-$8 for a yogurt.
The Casino is great and they have some of the best cocktail waitresses in any casino in Vegas.
The rooms have a pool view or mountain view, we went with the mountain view. Everything is the room is electronic which was a little weird at first but we got used to it.
Minus 1 star for the lock of a coffee pot in the room, they want you to order expensive room service or overpay at Starbucks. My suggestion would be to go to the Starbucks in the connecting mall next door. A lot cheaper if you don't mind a small walk. Or simply go down stairs and sit at a slot machine and ask for coffee.
The good thing about Aria is the connecting TRAM monorail which takes you between casino's. This helps you avoid all of the Vegas Strip street hustlers trying to petal show tickets all night. Go to the back of the casino and up the stairs, follow the signs or just ask someone.
ARIA is cool, you will have a great time!
