Jester, how'd you account for teleport magic?
Well, this is a 4e campaign, so there was only short-distance teleportation for me to worry about. So I didn't really need to worry about it (yet)... and since we had the six-year siege, I am satisfied with the amount of time the pcs will take to go from 1-30, even if they do the other 19 levels (they are now 11th) in six game days.
In fact, other than a few short-term teleport powers (fey step, dimension door, etc), a quest for a component for a priest wanting to make a "door" that the populace could escape through and a few monsters with minor teleportation (balhannoth!), teleportation hasn't come up yet in the campaign.
