My stay at Mirage was good as an overall experience. I've never stayed at Mirage and was expecting it to be on the same line as Bally's.
They have a poker room that runs smaller games, 1-2 no limit and 2-5 games, as well as 3-6, but it was surprisingly empty at almost all hours.
The rooms was what I expected, but my biggest complaint was that it was extremely noisy. You can hear conversations in the hallway from the inside of your room and then your neighbors's doors slam shut, it wakes you up.
The dining selection was also quite limited. There's a deli that's way overpriced, a burger joint that was decent, and California Pizza Kitchen, which has really good service.
It's also a short walk to the Caesar's forum shops which was also very nice. It's also just across the street from the Venetian.
My favorite part of the hotel is when you drive in, the palm trees really gives you a feeling like you're arriving at an oasis.
