Are you handy with a multimeter?
Take the negative battery cable off.
Hook the meter set for AMPS between the two.
Wait for interior lights have gone off.
A few milliamps of drain is normal in any vehicle.
If it is more than that, start pulling fuses one by one and checking to narrow it down.

How long is the car parked before it kills the battery?
Seems pretty low chance its an intermittent parasitic drain.

I once had a motorcycle that had a weird charging issue. In that case it ended up being a bad connector between my stator (alternator) to my voltage regulator/rectifier. When the volt meter was put down, everything looked fine, but after about three days of riding the battery would be dead. Replaced the connectors in the wire harness to the regulator and I was back to normal.
I'm taking it that in your case the car is not being driven over the eight days though, huh? All I can think at this point is to clip your volt meter between your negative connection and watch it. Do you have a wireless camera or a baby monitor with video to check here and there for a spike in amperage drain?
