Depends how fast you go and also the exact positions of each planet at the time you take off. For example if Neptune is on the same side of the sun as earth is when you take off, you want to be sure it'll be back in optimum position when you get there. at its closest, Neptune is 2.7 billion miles away from the earth. At the speed of light it would take you 14.5 seconds. But at more conventional speeds, let's say escape velocity, 12.2 years.

Voyager 2 launched in August, 1977. It arrived at Neptune in 1989. So 12 years for Voy 2. Unless you're a photon! Then, say, 5 hours.

Assuming a rocket travels at the minimum escape speed the entire journey (25,000 mph), it would take approximately 12.2374 years to reach Neptune. Neptune is 2.68 billion miles from here...
