I have been apart of 1 campaign that came to a close with an all night battle against 5 liches (3 to 4 12 to 14th level players) and then I've DM'ed 2 campaigns that will come to a planned end as well. I am currently on my 3rd campaign which is going along pretty well trying to avoid many of the pitfalls. Now its dependent on ending sooner or later.
But to answer the question: I would have the game come to a climax. Just because Helm's Deep was the climax of Two Towers doesn't mean the trilogy was over. You can leave a few loose ends you can pick up later when your group gets back together. But the reality is that it is hard to get that group back together again as time goes on. People move, get into relationships, fall out of interest. So better to end on a high note instead of just finishing in the middle of a dungeon and saying you'll pick it back up in 6 or so months.
