It is true that a body free-falling into a black hole will be ripped apart by tidal forces at some point. But that point might be deep, deep inside the horizon, almost to the singularity. So there can be a very large volume of spacetime inside a black hole where bodies are not ripped apart by tidal forces.

That's a misconception about black holes. The gravitational stresses inside a black hole can be quite mild for a period of time. Eventually they will become great enough to rip you to pieces, but depending on the size of the black hole, that "eventually" can be an arbitrarily long time.

As I understand it, the forces that would rip a body apart are due to differential acceleration as the body is drawn to the black hole. Is that correct?
