As someone said if the travel time was a month, I'd opt for a week, and I could stay for a week or 2 and return then I'm ok with it.
The human body evolved on this planet and I can't help but think living on Mars with such different gravity would effect your body. And what facilities would exist for healthcare, we can't do it here can we do it on Mars?
And another thing (since I'm on a roll
) people can't stay married for more than 3,7,10 years (yes I know many here have been happily married to your spouse for 30-50 years), how the heck will they tolerate the living conditions in such a restricted environment with nothing to do and nowhere to escape to? It just doesn't make sense to me but I'm an armchair adventurer. I've traveled the world to every place a camera can go from the comfort of my couch!
