Thing with taking humans to Mars is that these humans need to be confined in a small space for quite a while. Messages to Earth take longer and longer, so that takes phoning home on a whim out of the picture. On top of that, vacuum packed food even has a certain amount of time it can be kept. Also, drinking your own pee is not particularly a nice prospect, but a requirement on such missions.
What if there's a mechanical problem somewhere? Sorry, you can't quickly ask for a replacement part from Earth, and you still need to poop and piss. So you need to carry all of those parts along as well. Don't forget about the human body deteriorating in various ways, simply because there's almost no gravity.
No, Mars is totally not feasible at the moment, simply because it'd take too long to get there. Having a moon-base would make it more doable, as it becomes quite a lot easier to build a massive ship to accommodate three couples, so they won't go insane and murder each other, have enough spare parts, and have enough food stuffs to reach Mars and go home again. What you'd need to get there would need to be massive, and something of that size simply can't be launched from Earth, but it can be constructed a lot cheaper in orbit of the Moon.
