Hyperspace travel speeds seem pretty vague and inconsistent in the Star Wars universe, but I have seen a number of videos and websites estimating somewhere around 25,000 light years per day (depending on the ship, of course). Assuming the Star Wars galaxy is roughly the size of the Milky Way, it would take around 4 days to travel from one end to the other, effectively making interplanetary travel a non-issue that is rarely brought up.
At these speeds, it would only take 3-4 months to travel the 2.5 million light years to the Andromeda galaxy, and a number of other nearby galaxies could be reached in less than a year. This is not ideal for sightseeing or business trips, but it would be perfectly reasonable for exploratory or scientific operations. I imagine making ships large enough and comfortable enough for such excursions would not be unfeasible either.
Is there a reason why this is never done? (or is it?) Fuel costs? Risk? Simply no practical need?
