Yeah, those things can often be pretty much the same.
Worst I've ever had was a ten-member party got split ten ways by a wild magic effect teleporting each of them to a random place within the rather big dungeon they'd been exploring.
I stopped the session at that point and sorted it all via copious amounts of email during the week, during which I had little chits on the map telling me where each one was.

By the start of the following session I think something like eight of them had reunited, we then roleplayed them looking for the other two (one was asleep thus easy to figure, the other was trapped and had to be rescued).
