For some food for thought on minimums.
For a pilot in command to be able to be hired to fly your family on the same IFR flight the minimums are
1200TT, 500 XC, 100 night, 75 instrument, 50hrs of that need to be in flight.
NOW, since it's YOUR family and YOUR plane and YOU are going to be PIC, it's just pt91, so you only need a PPL with 50hrs of cross country, which can consist of mainly tiny 50.1nm "cross countries", 40hrs of actual OR SIMULATED instrument time, one 250nm x/c with a CFII, a written and a checkride.
Pt91 gives us a lot of room to make our own decisions, you can see the huge difference from how many MINUMUM hours are required to hire a pilot to make the same flight with your family aboard in IMC and how many hours for you to launch into IMC with the family aboard, my point is I would want above the pt91 minimums to fly my family around in IMC.
