Like I always say (like a broken record, or a tape loop) -- transfer them now, once and properly.
Proper baking, excellent analog playback, high quality digitization, good digital file management.
Then you won't _need_ to bake them for 10 days sometime later (you may _want_ to, but that's another
matter).
