In the sing-off, Princess Courtney is seen singing with hold the microphone in her left hand. When Erika Juno and the Camp Royalty students appear onstage, the microphone is in her right hand. Finn calls Camp Royalty an "outdated Charm School," which is a reference to the titular school in Barbie: Princess Charm School.

The campers were unaware of the losing camp having to close until Erika overheard Lady Anne's assistant, Clive, talking about it. Clive also said that he had bribed Svetlana to vote in favor of Camp Royalty. Being royalty himself, Prince Reginald would already be biased towards Camp Royalty, whereas Allegra would be biased towards Camp Pop as she is a musician. Teresa Espinosa, who did the dance choreography for Barbie The Princess & the Popstar, also did the choreography for this movie.Both non-princesses posess a magical object (Erika is given a magic scepter by Princess Olivia later in the movie)

The microphone now is in her right hand, a few times after Erika and Camp Royalty students were come into the stage.

Did we miss something on diversity?

Marcus's drum kit is wrong. There are too many cymbals and has an extra bass drum. This is a problem similar to the character Courtney in The Barbie Diaries. Descriptions for the Mega Bloks merchandise for the movie say Princess Courtney and Erika are named Emma and Harper instead. Courtney often gets asked questions by the kids at Camp Pop referring to the fairytale Cinderella; first Sloane jokes about her being a Cinderella who "took the wrong turn on her way to the ball", then Rayna asks her if she has any evil stepsisters.
