Well, keep in mind that the operative equation is Distance = Speed x Time ! Even if speed could approach light speed ( which is highly UN-likely ), travel times to even close neighbors wuold be prohibitively long....
Actually, a speed close to the speed of light would only take years and years from the perspective of observers here on Earth. To a traveler on that spaceship, the travel time would be lots faster. In fact, to anything traveling at the speed of light (which, of course, is impossible), the travel time would be ZERO. That's right, you could travel across the galaxy or even between galaxies in zero time, the distances involved would be irrelevant.
