OK serious answer to your question.
It depends on each partner, but I would have thought for a really enjoyable time you need to be avaiable - and I mean body, soul and mind here - for at least 4 hours. If you are worrying about timings, having to explain your absence or getting back for the boss/babysitter then that will reduce the pleasure for both (all) of you no matter how long you have.
Personally I always want to spend the whole night or day really getting to know someone - even if it'll just be the once. As a few have said a quick shag is avaibale 24/7 if I'm not too fussy. Which I am, so that explains why I don't do that.
