 I'm using apt-cron also and I set it to just download the packages and 
 send me an email if there's something to update. Then I log in and do 
 the update manually (apt-get upgrade / dist-upgrade).
 If you have lots of servers, that wouldn't be practical I guess. But 
 for 1-2 servers I think it's not a big deal (IF you look at your emails 
 fairly often, like once a day?).
