Mine is outside for its summer hols on a north facing terrace so lots of light and no direct sun. First time I've done this so it'll be interesting to see if that makes a difference. Normally it's just the big ficus elastica and benjamina that go out.
Otherwise, my Xmas cactus lives in a well lit room with very thick walls so it only gets direct sun when the sun is horizontal in winter and only gets moved for an occasional rinse under a shower tap to remove dust from the leaves.
