Basically it depends on the level of your technology and the amount of fuel you wish to use. Fuel is expensive, and getting it into orbit makes it much more so. Its perfectly possible to get to mars within hours or days, but you would bankrupt the planet doing so. And again Gothika is correct: the limiting factor, other than economics, is acceleration. Its perfectly possible to launch stuff into orbit using a rail gun. One minor problem: any astronaut using such a method would be turned into a gelatinous goo by the acceleration. This is why NASA uses rockets instead of insanely large guns. And a quick observation: When I first came upon Gothika's icon I figured whatever he had to say would be worthless. It was so strange looking. Then I read his answers and discovered he is completely on top of things. He's obviously far more educated in this field than I am. Gothika gave a great answer.

Assume a ten day visit... Then the return flight would be another 5 1/2 to 6 Months. Please note that the flight is not a straight shot (as in line of sight...). Also, the flight will most likely be staged from the ISS and consist of multiple launches from Earth's surface to get all the equipment up into orbit first. This has not been reported yet, and is only my guess. Roughly 5 1/2 to 6 Months one way…

Anyway, since you wish to ignore acceleration (you only mentioned velocity), so 99.999999...% of light speed (you can't go at light speed or faster) ... um probably a few minutes.

If you had enough fuel, you could have constant acceleration/deceleration (accelerating for half the journey, decelerating for the second half) at 1G (9.8ms^-2), which would take about 2 days. But we can't do that yet, as we have no appropriate fuel/technology to do so. 6 months, at a close orbit, using current technology.
