2 hours? I don't think so.
Well, like I said, there's plenty of argument out there that supports both sides. For me, the jury is still out.
Do a google for "How long does it take to travel from Tatooine to Alderaan" and see the results. There's lots of arguments for 2 hours.
Alderaan is in the Core worlds. Tatooine is in the Outer Rim. If it only took 2 hours go get from one to the other, the Outer Rim would not be lawless.
You're thinking too linearly. Hyperspace is another dimension where spacial distances are distorted. That's why hyperspace routes are so important. They're the name of the game. You could have planet Core Worlds with two like vessels heading to the Rim. One ship takes a hyperspace route that is fairly straight (meaning clean of obstacles). The other ship takes a route that avoids a lot of astronomical obstacles. The first ship might reach its destination in a few hours where the other vessel's trip will take days.
Likewise, a ship taking off from a planet in the Rim, heading to the core worlds, could take a major trade route and be there in hours. The same ship, taking off from the same world, could use an old, outdated smuggler's route to a world in the same sector--very close, astronomically speaking, and also in the Rim--and get there in days.
