We were just in 5066 and while it was clean and conveniently located, it was over the service area and the compressors were quite loud. Not loud enough to hear in the room, but loud enough to keep us off the balcony.
The good news is that we could see the fireworks thru the trees every night. That was pretty cool!
You may want to ask about an upgrade...
Good luck. You'll be happy to be there, no matter how lousy the view.
