Just say "away from the Carnival Court." (If it has reopened by then, and still plays horribly loud music late into the night).
The construction noise is not a problem at Harrah's - yet. We have stayed on the back side of the Carnival Tower many times, and while we can see the Linq High Roller constuction over to the far right of our windows, we have never heard any noise.
Also: The sunrise from that view is spectacular.
The Mardi Gras tower is probably furthest away from the construction. But you may not want to be on the Carnival Court side (again, because of the loud band playing).
