A 4-day base ticket is a standard theme park admission option for Walt Disney World that allows you to visit one of the four major theme parks—Magic Kingdom, EPCOT, Disney's Hollywood Studios, or Disney's Animal Kingdom—per day for a total of four days. Unlike "Park Hopper" tickets, a base ticket does not allow you to move between different parks on the same day; once you enter a park, you are committed to that location for the remainder of the day. In 2026, these tickets are date-based, meaning you must select a start date at the time of purchase. A 4-day ticket typically comes with a 7-day usage window, giving you flexibility to take "rest days" in between your park visits. This ticket is often the most economical choice for families who want to dedicate one full day to each of the four main parks. Prices in 2026 vary significantly by season, with peak periods in November and December seeing higher rates than late summer. If you want to visit water parks or play miniature golf, you can add the "Water Park and Sports" option to this base ticket for an additional fee.
