If you have a multimeter, go to the fuse panel and using the current setting place your leads across the fuse holder with the fuse removed. If you indicate any current flow, then you found the source. You can see what that fuse is feeding from the panel legend to fix the root cause. Make sure your multi-meter leads are in the correct slots on the meter before you do this, otherwise you may blow a meter fuse.
I've got an older Camry as well. 180,000 miles and still runs great.
Sounds like good advice for tracing down the problem. If a person just wants to treat the symptom without finding the source of the problem, you might just install a switch of some sort that will open the connection from the positive battery cable to the battery. If you don't want to get a switch, then just disconnect the battery if you know that it is going to sit for a long time. But I believe Mr. Hooberbloob offers good advice for tracking down the problem. If you don't know how to use a multimeter, you might simply remove the fuse to the suspected source. If the battery continues to drain, then next time remove a separate fuse. When you finally remove the fuse that stops the battery from being pulled down you can trace that circuit down further, and check for bad switches or sockets. If you have had any work done on the car before it started acting this way, then you might want to see if any damage was done in the area of the work.
