When the girls (and Anthony) go shopping at a mall, the establishing shot of the mall's exterior entrance is actually a view of the former Plaza Pasadena mall, in Pasadena, California.

Charlene talks about visiting a town in the Georgia mountains that is modeled after a Swiss town. The town, Helen, is actually modeled after towns in the Bavarian state of Germany.
