People have been pointing to space tourism for decades, but I've never thought it viable. You quickly run out of people with enough money to pay what it costs to run the service.

Beyond that, it's got to be the lousiest way to spend a couple days. Weightlessness is really uncomfortable -- you're most likely going to be motion sick for a day or two. But beyond that your body requires gravity for proper distribution of fluids. The reason astronauts look so puffy in photographs is their faces are swelling from excess fluid.
