I have the same issue with our Honda Odyssey. I traced the drain to a single fuse but that circuit splits to many modules such as keyless entry, clock, power doors-seats, etc, etc and I would need to remove the interior to troubleshoot-not worth it. It can go for about 2 weeks before it won't start. I never understood why it needed a new battery every few years but the drain was ruining the battery by it being partially discharged all the time. My solution is a battery tender plugged into the ceiling with the plug hidden in the grill. Problem with battery disconnect is a lot of things need to be relearned everytime.
