Do those Aria rates sound enticing to you? It's been a very long time since I've reserved rooms here, but they sound a little steep for a slow time of year in a hotel that is hurting and can barely average lukewarm reviews.
The buffet was very disappointing to me, and I've heard they are working on cutting back to help the bottom line $$$. The $50 freeplay divided by the two of you over your stay isn't much.
OTOH, the Wynn has been going through a top to bottom remodeling project on their rooms, and I think it's about complete.
If you are a loyal MGM, MRI customer, then the Aria is the crown jewel and worthy of a try. I'd be interested to hear what you think about it, especially compared to $30 higher Wynn room.
