I don't hate them, but I don't enjoy them the same as I do Epcot, and MK. I can have fun for one day in DHS, or AK, but for me they aren't multi day parks.
If someone comes on the DIS and asks which park do I skip if I only have three days to spend, then I will suggest skipping DHS, or AK.
However, if it were at all possible, I would make sure to plan for at least four days in the parks, so no park would have to be skipped. Driving to Florida from NY, it would be an incredible waste of time and money to spend only 3 days in the parks for us anyway. We will have 11 days in the parks this year. Even with that many days to spend, DHS, and AK are one day parks for us. That doesn't mean that we can see and do everything in the parks in one day, but there isn't really enough there for us to make either a two day park, so the things we miss one year, we make sure to see the next.
I would go to DHS just for TSMM, even if there wasn't anything else in the park I enjoyed. Star Tours is great fun, we love the Sci-Fi Dine-In theater, Lights Motors Action, Indiana Jones, and Block Party Bash. Fantasmic is a great show, and we're really hoping to see Beauty and the Beast this year, as we haven't seen it yet.
In AK, the Safari is fantastic, we love the walking trails, and the Tree of Life. The parade is one of the best in Disney World, and Festival of the Lion King is worth the trip to the park by it's self.
