The galaxy is a small place now. Smaller than ever before.
Does it make the galaxy smaller? Sure. But it doesn't bother me. With films like these, so much depends on the crew running on adrenaline, action scene to action scene. So even though we don't see it from an audience perspective, those six travel days would be just as unrealistic for the characters to remain amped up and ready for action.
It's just a trade off.
