Where did they came from when you sat on your arses for a week? Gee, I wonder! Seems like an attitude problem, not a game problem. In an adventuring game there usually is some sort of a situation/crisis/conundrum going on, that needs solving, and you just cant dillydally for weeks at any moment. I really don't understand what sort of static games people are running if this is not the case.
It doesn't need to be that many in one week, as there can be some uneventful days between them, just not a whole week of nothing. But ultimately a huge chunk of D&D's rules are about combat, so if people don't like playing in style where combats are at least somewhat frequent occurrence, they're playing the wrong game to begin with.
