Here's a review from January of this year from someone who had problems with the noise from the theater in 9500: Link.
"Speaking of noise, one big drawback of this suite is that it is right above the theater below. That means, almost every day around noon, you will hear them rehearsing for the shows. Then, at night, you get to enjoy two shows almost like you are in the theater. I mean it is LOUD. We often went to early dinner and then the late show as we had no chance of sleeping early if we wanted to."
