An Aldrin Cycler cruise ship is just the thing if you want to take tourists around the moon.  Aldrin Cycles are multi-phase orbits between the Earth & Moon* where you can keep heavy orbiting with low delta-V requirments.  Tourists can boost from earth in a small shuttle then enjoy the luxuries of open spaces and big windows as they make a comfortable trip around the moon.
