HardCoreGamer,
POR has 2 different sections, with different styles of buildings, Mansions and "Alligator Bayou".
The mansions are 3-story buildings, decorated like southern plantation mansions, and landscaped with large lawns and formal gardens.
The AB buildings are themed more like bayou homes, set in a more densely landscaped area, with winding paths, trees, ponds, and a more rustic feel. They are smaller two story buildings, and also feature a trundle bed so they can sleep 5 people instead of only 4.
Both types of buildings are situated along the "Sassagoula River".
Does that answer your questions?
