There's the issue, the ceiling in question wouldn't be considered a floating cloud, (my point), with just small openings for return air.
I envision the floating clouds as those panels scattered throughout an area intended for acoustic absorption or architectural flavor but not necessarily attached to each other or to walls. We're talking of two different things here apparently. Craig L.

You copied all the other opinions except mine. You may have been referring to Craig's response. Bob and I are on the same page - floating clouds are obstructions, not the ceiling. Now I did run down a tangent and mentioned a small opening (up to 12 inches) at the edge (and only the edge) of the room. That one has room to discuss not putting sprinklers above the ceiling (which isn't a floating cloud).
