The heater core leak is becoming pretty common in this age NB. I replaced mine last summer. The old heater core was just kind of weeping along one end of the core so it was just damp. I never saw coolant actually drip and there wasn't much inside the housing when I took it apart. The car became pretty much unusable in subfreezing weather. The windshield would fog up easily and turning on the defroster just made things worse.
You probably have a second leak where most of your coolant is being lost. The plastic coolant flange where the upper radiator hose connects to the cylinder head is another common source of leaks. I replaced mine along with the o-ring a few years back now.
Then there are the 22 coolant hose ends to check as well!
