Both the princesses have a magical object. For Tori, it is her hairbrush. For Courtney, it is her scepter

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. Courtney says she pranked a duchess by turning the her portrait into that of a donkey. Tori pulled this prank in Barbie The Princess & the Popstar. The unicorn doll that made by magic from Princess Aubray's scepter was similar with an unicorn doll named Buttercup from Pixar's Toy Story 3. 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. When Zia asked Courtney if she'd ever turned a frog into a handsome prince, she was referring to the fairytale The Frog Prince.This is the second movie that Kelly Sheridan voiced another character besides Barbie (Svetlana Petranova), the first one is Barbie and the Magic of Pegasus. 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.

Finn calls Camp Royalty an "outdated Charm School," which is a reference to the titular school in Barbie: Princess Charm School. Unicorn doll from Princess Aubray's scepter (left) and Buttercup from Toy Story 3 (right).There are portraits of Alexandra Privet, Duchess Amelia, the royal judge from Barbie: Princess Charm School, one of Keira's dancers, and King Terrance in Lady Anne's office. The microphone now is in her right hand, a few times after Erika and Camp Royalty students were come into the stage. Also Known AsMarcus'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. Both non-princesses posess a magical object (Erika is given a magic scepter by Princess Olivia later in the movie) Descriptions for the Mega Bloks merchandise for the movie say Princess Courtney and Erika are named Emma and Harper instead.
