Any one stay at the Aria hotel before? Is it nice, close to attractions?
I've visited Aria many times, but I prefer staying elsewhere since I get casinos comps at other properties. Although, I have a few friends who like staying at Aria. They said that their rooms are very nice, as well as the room views, pool, etc.
Aria is closer to the southern end of the LV strip, so it depends one what attractions you're interested in seeing. The new T-Mobile arena is next door behind the Monte Carlo, as well as The Park between NYNY and the Monte Carlo. I know a lot of folks who prefer mid-strip, since there are quite a few attractions within walking distance like the Bellagio fountains, Mirage Volcano, Caesars Forum Shops, High Roller at the Linq, Wax Museum, etc.
Just be aware that many places now charge for parking on the strip unless you're a mid-high level gambler in their players club. That includes self-parking as well as valet parking.
COH also has a thread about Vegas hotels which may interest you...
