I don't wake mine up either. I don't force them into brumation either, for that matter.

Two woke up around Christmas (unseasonable warm weather) and two more are fast asleep. One is an elderly gentlemen, so I let him rest as much as possible. The other is my breeding female and likewise, I prefer to let her rest. I'm kind of a "au natural" kind of zoo keeper around the house.
