I'm not a crate and rotater, but I do work in a kennel full of dogs that for the most part don't get along, so I would think that key would be as equal as possible. I would think less frequently would be easier on you, and really it might teach the dogs to have more down time...
I can only please one person per day. Today is not your day, tomorrow doesn't look good either.
