Barbara - I had a lengthy conversation with Randy @ DamppChaser this morning about a number of things, including this. His take on "unplug", if he doesn't mind my summarizing, was that the soundboard is much slower to acclimate to a change in condition than the couple of hours your system would be disengaged (taking into account all the caveats that have been already aired). He felt that temperature change would be much more of a factor, short term, than humidity. Of course, what I didn't think of at the time was whether the absence of any heat source under the board, for that period of time, would represent a "temperature change". Not what I think he had in mind. If you truly felt the need to stay 'powered-up', but were genuinely concerned for the welfare of the choir members, you might look into using something like a battery back-up, like we ALL use for our computers. If the piano is mounted on a dolly (given your description, it sound like it should be), you could just have that mounted on said dolly and plug into that. And then, there's just tacking down the extension cord with premium gaffer's tape, my favorite tool.
