Toyota Repair: 2004 Camry battery keeps dying, battery down, 2004 camry

Question
I have a 2004 Camry.  If we don't drive the car for three to five days the battery goes dead and needs to be jumped.  This has gone on since we bought the car in 2005.  We didn't notice it at first, because the car was driven every day.  I have replaced the battery three times now, the last two times was from the dealership.

I have taken the car in three times now leaving the car for over three days and each time the tech tells me that it is drawing the normal load on the battery when it is not running.  They have tested the alternator and everything checks out normal.  They cannot tell whats pulling the battery down.  

This is really getting frustrating for me and my wife.  Do you have any suggestions?

Answer
I agree that it should not draw the battery down in that time period, I know the dealer said there is no excessive draw but my question would be if they told you exactly how much current is being drawn, everything can't be normal or you wouldn't have this problem, have you checked to see if the brake lights may be staying on, dome lights etc? Can you get a digital volt/ammeter so I can help you check the draw yourself?
