Disney World is undergoing significant construction in 2026, with closures and new themed areas in Magic Kingdom, Hollywood Studios, and Animal Kingdom. International travel trends and discounts suggest that park attendance may be lower than expected. New attractions and experiences are opening in 2025 and 2026, but major new lands won't be available until 2027. Despite construction, peak seasons at Disney World are still expected to be crowded, making 2026 potentially a good time to visit for those looking to avoid large crowds.
