I don't get all picky about how much time actually passes in Empire because it's related to how far these systems are from each other and its a point that people get so hung up .. partly because people know that the in real life the distance between stars is just so big.
It is a fantasy. The Falcon is a ship that can travel through space. We have cars and planes capable of taking us to other places.
I always look at it this way. I live in Eastern PA. The two destinations I have in mind are NYC and Orlando FL. NYC is a relatively short distance away, and I'd use a car. It would not make sense for me to use a place.
By comparison, the Falcon, and every other ship, is capable of going the relatively short distance between Hoth and Anoad. they probably don't even need the hyperdrive any more than I would need a plane. The ship's ability to go between these systems is not anything scientific.. it's just what a ship does. Nothing else is scientific about Star Wars, why should traveling between systems be? The ships are designed to fly to different systems just like my car between different cities.
Ok, so the Falcon has trouble with the hyperdrive. it made it from Hoth to Anoad, but it's cant really escape from the Empire here.
So back to my car analogy. I am in some trouble. I need to get out of Pennsylvania. I can go to NYC but its not far enough away. Preferably, if I could get to Europe I'd be in the clear, but I know a guy that can help me in Florida. All things being equal, I'd fly to Florida, but let's say I can't for the same reason I can't fly to Europe. I can drive to Florida.. its a bit far but something I can still do. I can't drive to Europe.
Similarly, the Falcon has no hyperdrive, which might take it to "the other side of the galaxy" as stated in the film. It can still go between systems that are nearby without it, but it can't truly escape without the hyperdrive.. no more than I can get to Europe without a plane. Bespin is pretty far from Anoad, but, just like Florida is driving distance for me, Bespin is a system that still is close enough (barely) that the ship could still go there without hyperdrive.
That's how I look at it. These films were never about the science. The character's might call it "light speed" but it was really something else entirely. All those books that explain away these technicalities and all those debates that bring up the problem of interstellar travel in Star Wars are pretty much missing the point.
