Of course I've come to think that the travel times are not consistent with what we see in the movies. Okay, we didn't have a lot of information to go on with the original three - but take Phantom Menace for example. Maul gets from Courscant (the inner systems) to Tatooine (the outer rim) in just a Tatooine day.
Actually, we have no real idea how long anything took to happen as the director just jumped from sequence to sequence. How long does a sandstorm last on Tatooine? Well, we don't really know, but sandstorms on Mars, a similar type of world has storms that last for weeks or months at a time.
We have no idea how far apart the worlds really are, other than some vague terms. Even if they are in setup in rings, are the worlds on the same side of the rings or the far side from each other? Writers and Directors don't really seem to care about such things when setting up their stories. That's just too much detail that interferes with the writing. Just look at shows like 24... the show supposedly occurs in real-time, yet getting across LA at most times of the day can't occur inside the span of one episode, yet they do it repeatedly throughout a season.
For another example, the hyperdrive wasn't functioning on the Falcon, yet they were looking for nearby SYSTEMS not planets in their current system to go to, yet they clearly arrived in less than a year, which is why WEG had ships equipped with backup hyperdrives that are significantly slower than the main drive.
