The hotel manager is voiced by Mr. Moseby (Phill Lewis), the hotel manager from The Suite Life of Zack & Cody.
This is sort of a reunion for some of the cast of The Suite Life of Zack and Cody: Caroline Rhea, Alyson Stoner, Ashley Tisdale and Phill Lewis.
Part of the inspiration for this episode is another Hawaian adventure from another TV show, "The Brady Bunch," specifically the episode called "Pass the Taboo."
