No place lacks tourism potential.
However, the Saturn Subsystem is an obvious choice with over 62 moons with some yet to be named and not counting the small moonlets that make up the spectacular rings.
Titan has a toxic atmosphere like that of primeval Earth and has actual lakes and rivers though not of water.
Enceladus has ice volcanoes.
Saturn itself has poles with unexpected patterns and you can watch lightning displays and auroras in its atmosphere.
