the aria was nice but I wouldn't say its the best hotel in vegas.
its pretty big nut not nearly as big as some of the other hotels that require a mile hike just to get in and out of.
there is nothing spectacular about it. the décor is nice and chic but kinda minimalist in comparison to the other vegas greats.
the rooms are large and the smart technology is great. I wish the bathroom would've been a little bigger (and it would've been super cool if the wall was glass in the shower to be able to see out of the room floor to ceiling windows).
the service was good but check in was a LONG wait. about 30 minutes standing in line and it was only 9 am. they did have a great feature where they gave us room keys and text us the room # when it was ready so we wouldn't have to wait in line again.
overall it is a nice hotel in a great central location on the strip, I would stay there again especially with the awesome rate we got 155/night.
