If your sending up "tourists" for a week in a tin can, an equatorial
orbit is optimal for radiation purposes. Remember, the Van Allen belt
become lower in altitude the closer to the poles one is.

If these folks are for real, if they're really lucky they'll be up and going just in time for the next solar max....

Hmm...

"The Neptune Orbital Spaceliner is now in development and will be made available upon certification for orbital tourism operations. It will be capable of placing two pilots and four tourists into polar low-earth-orbit (LEO) for a period of up to seven days. Its novel habitable orbiter stage (HOS) will provide a spacious living area while in orbit. Tourism flights are slated to begin as early as 2005."

Yea, 2005 sure. I hope they're planning to have a shelter of some sort.
