The private island is a location in Barbie in Rock 'N Royals. On opposite sides of the island there are Camp Royalty and Camp Pop.
At the end of the movie, Lady Anne (the director of Camp Royalty) and Finn Oxford (the director of Camp Pop) make the decision to merge the camps together starting the following summer. It's unknown what the new camp ends up being called (possibly "Rock 'n' Royals").
