You say that Lloyd but you also dont say that you backup cards before leaving the venue so I am guessing you dont ?. I think anyone who doesnt backup before leaving the venue is being cavailier and I dont understand why more people dont do it, if the first thing you do when you get home is backup your cards then you may as well just stay at the venue another half hour and do it there surely.
Like Tim, I don't find any real benefit in backing up before leaving the venue. If you lost the images from the church ceremony, there's little you can do with a tired, drunken couple at a reception hall.
The first thing I do when I get home is shower and go to bed... 
I don't look at the cards until morning. Not much can happen between getting home and waking up.
