So, we decided to go with Aria and they have been amazing!! Julie there has been amazing. We were originally booking with mirage and they were less than helpful. The lady I dealt with bluntly told "no discounts for group rates" Once she found out we were under 65 rooms, that was pretty much the last email I had from her.
Anyways Aria was quick to get back to me and we had a group rate and block of rooms set up with in a day. They gave us a great deal better then we first quoted.... I asked for 35 rooms and she emailed me back and said "oh I didnt realize you want so many rooms. I will get back to you shortly" so she up our discount and I think she upgraded our room for us.
I am so glad that we changed hotels!
