To truly experience both resorts in 2026, you should plan for a minimum of 7 to 9 days. For Walt Disney World, which consists of four massive theme parks (Magic Kingdom, EPCOT, Hollywood Studios, and Animal Kingdom), you need at least one full day per park, plus an extra day for rest or revisiting favorites, totaling 5 days. For Universal Orlando Resort, the recent opening of Epic Universe has changed the math; you now need at least 3 days to cover Universal Studios Florida, Islands of Adventure, and the new third gate. If you include travel days and time for the water parks (Typhoon Lagoon or Volcano Bay), a full week is the bare minimum for a "highlights" tour. Many international visitors opt for 14-day "Unlimited" combo passes to avoid rushing, especially since the physical distance and security screenings between the two resort properties can eat up significant portions of your vacation time.
