I've just been to a couple of retreats and didn't realize how lucky I've been! We are so fortunate to have three rooms, so we have sort of a Goldilocks situation -- one room for the "wild and crazy" guys, one for the "silent and serious" guys, and one for those of us who are mostly quiet but have many laughter eruptions -- Just Right (at least for me). So far in my room, anyway, no issues re cell phones, new machines, etc. Room temp anywhere can be problematic, depending where gals are on the menopausal scale! Dressing in layers is a good thing.
