Why put a station at an L-point? It's my understanding that only L4 and L5 can be maintained without adjustment propultion, and they're really not any better than looking from Earth. I'd say just put it in orbit.
In any case, I doubt anyone is seriously thinking about establishing a long term space-based colony so far from Earth for the short term. If something goes wrong, you have fewer backup options than if you're on solid ground. Perhaps, once spacecraft with ion drives become reality, but when it's a multi-month trip, terra firma is comforting.
I meant in the Earth/Moon system, and was simply pointing out that we didn't have to colonize Mars before having people taking pleasure trips there, was the point of my previous post.
I also agree that this type of thing is quite a ways into the future, as we don't understand enough of how to counteract low/no gravity effects on the human body (and low gravity has only recently begun testing).
I seem to be having a serious problem with communicating clearly, heh. Probably too scatter-brained posting at work...
