I never use cliffhangers, they don't work well in a sandbox campaign with varying parties. They start every expedition at their HQ, they end every session in the HQ, to avoid problems like "oh we finished in the middle of the dungeon last time but Pete couldn't come, but have to add Bob's character", plus it makes it much easier to handle the campaign. They do have lots of unfinished business, usually related to their long-term goals, which will keep them interested.
