Brenda Song's character of "London Tipton" the hotel owner's spoiled daughter, is an obvious play on hotel heiress Paris Hilton.
Ashley Tisdale tried out for the roles of both London and Maddie.
The Tipton Hotel where the show is set is supposed to be in Boston, Massachusetts. The hotel exteriors shown in the series are not actually the Fairmont Hotel in Vancouver, British Columbia, like some rumors say, but are computer generated.
In the original script of the show, Maddie Fitzpatrick's name was Lena.
The twins said in an interview, that their names on the show were actually named Dylan and Cole, as the characters were based around them, But as the story progressed, they changed their names as the twins' and the characters personality's' differed.
The executive producer pulled Becky Rosso and Milly Rosso from the audience to play the twins' girlfriends.
Maddie's full name, according to her, is Madeline Margaret Genevieve Joanna Miranda Catherine Fitzpatrick.
