The government is in the process of issuing regulations for space tourism:

The FAA's Associate Administrator for Commercial Space Transportation (AST) has already issued draft guidelines for those ready-and-wanting space tourists among us.

Under a new regulatory regime, you as a paying passenger will be able to zoom into space sitting inside a commercial space vehicle once you've been informed of and assume the significant risks of the venture. Additional rules yet to come, FAA officials explain, will help promote the emerging commercial human space flight industry, putting it on a solid regulatory footing.

I would allow a large number of successful flights first before venturing outside the atmosphere, so they can work all of the kinks out of the system.
