Seems completely feasible to me.
Starting with Virgin Galactic, and space ship one, they're looking to get two people at a time into orbit and back. I know Branson has been trying to get a module on the international space station as a form of Hotel.
NASA is also starting to try and push space exploration and colonisation of neighbouring planets/orbiting bodies.
NASA - Orion Crew Exploration Vehicle
Starting with the moon by 2020, I heard that a modification of the Orion design will allow transport to Mars. I think they were talking about 2050 for the Mars trip though. The idea being a base on the moon with the additional modules then departure to Mars from the moon base.
It's still quite expensive though.
