Although it's Heroic tier (level 5) I would recommend Heathen from Dungeon #155, based on Heart of Darkness/Apocalypse Now, it has a great sense of drama and desperation, and by far the best climax I've seen in a 4e adventure. It has around 10 encounters which for me would take around 3 4-hour sessions, which might be a bit short, but the quest/journey format is easy to expand; eg the Banite camp could easily make a session's play.
I would be worried that a 30-encounter adventure like King of the Trollhaunt Warrens would take you more than 3 days and go unfinished, but perhaps it could be cut down to around 15 encounters, with more stuff added in if it looks like you'll run short.
