The motel where Jack and Kate found Aaron’s grandmother, Carole Littleton (“The Little Prince,” Ep. 5×04), was the Pacific Marina Inn near Keehi Lagoon (2628 Waiwai Lp.). Presumably, the same location was used when Kate returned to deliver Aaron later in the season (“Whatever Happened, Happened,” Ep. 5×11).
