If you're planning a trip to Disney California Adventure and you only have one day then I've created a possible plan for your group to follow and go on every attraction. You can do everything in one day at DCA using the following plan in conjunction with the official Disneyland app that shows you wait times.

Yes, in 2026, Disney California Adventure (DCA) absolutely requires a full day to experience properly, especially with the continued popularity of Avengers Campus and Cars Land. While the park is physically smaller than its neighbor, Disneyland Park, the complexity of its modern "E-ticket" attractions—like WEB SLINGERS: A Spider-Man Adventure and Radiator Springs Racers—often results in long wait times that can eat up several hours of your day. Additionally, the park features a sophisticated food and beverage scene, including the Lamplight Lounge and Pym Test Kitchen, which are best enjoyed at a relaxed pace rather than rushed. To see the "World of Color" nighttime spectacular, you must remain until park close, as it is the emotional centerpiece of the experience. While some "park hopper" veterans attempt to do both parks in one day, doing so usually means missing out on the atmospheric details and the variety of shows like the Disney Junior Dance Party! or seasonal festival offerings.
