Our sixth stay here and there is a reason we keep coming back.
We have been lucky enough to have stayed at most of the 5-star hotels on the strip but keep returning to Aria. Part of the reason is location but so much more. It still has a very modern, clean feel to it. It is not as ultra elegant as Bellagio, Mandarin Oriental, Wynn or Encore (we stayed at all) but is just great "upscale Vegas." Our favorite Vegas restaurant is here as well (see my reviews for Sage).
I won't repeat much of what my past review said about Aria but I would suggest registering with MLife, then look for a great deal here. We always think about staying elsewhere but there is a reason we always wind up back at Aria. And by the way-we are ALWAYS glad we came back!
