The Disneyland Adventureland Treehouse opens November 10, 2023! The updated treehouse will go back to its inspiration of Swiss Family Robinson. However, it’s not completely based on the original movie. Instead, it has new characters like a father, mother, twin sons, and daughter who all have stories told within the different rooms. Guests explore the father’s studio, mother’s music den, the sons’ nature room and the daughter’s astronomer’s loft.
