Outstanding artworks on display throughout the Aria casino complex. Each art piece is jaw-dropping amazing and complex. Skip the Aria app from Apple (hasn't been updated since IOS8) and instead pick up a brochure from the Aria Concierge Desk near the Louis Vuitton store.
It's a bit of an Easter egg hunt to find/see all the artworks, but it's well-worth your time if you have 4 hours or so and want to see every piece. I only saw but appreciated every single one.
The special James Turrell installation inside Louis Vuitton requires a month-in-advance appt...minimum, but would be well-worth it. Phone is: (702) 730-3150.
Mt favorites were the James Turrell "Shards of Color" by the elevator, Jenny Holzer's LED display outside by valet parking and the wall of water, also outside by valet parking.
