On an Adventures by Disney vacation, guests are taken on themed expeditions that often feature activities designed just for kids (or 'Junior Adventurers'). Two Disney-trained Adventure Guides (Cast Members) look after a group of no more than 40 guests on an Adventure, and are described as being 'part concierge, guide and storyteller'. Local guides also join the vacations at various points and give guests firsthand knowledge from someone native to the area.
