The limited amount of daylight is often an issue at this time of year, but that's not relevant to you since you can probably do the whole thing in under 6 hours!
Snow and ice accumulate in the shaded/protected areas but I think the fall storms this year haven't deposited enough yet to make it an issue for this weekend.
For most people, a December attempt is probably crazy, but somebody with your experience can probably do it with few issues.
I'd consider joining, but already have plans this weekend. Have fun!
