Each Disney park has different operating times. The times vary by park, time of year and other factors. But there are some guidelines that you can use to determine park opening and closing times.
The less-popular parks close earlier than the more-popular parks. At Walt Disney World, Animal Kingdom usually closes at 5 p.m., while Magic Kingdom usually closes at 9 p.m.
Parks have different operating times depending on the season. They stay open about 3 hours later during peak seasons (like summer) than they do during other times of the year.
Different parks have "Extra Magic Hours" each day and will either open 1 hour early or stay open up to 3 hours later, but only for guests staying at Disney-owned hotels.
Occasionally, parks will have special ticketed events. These events take place after the park has closed. You will need a special ticket or wristband to get in during this time.
Different attractions sometimes have different operating hours than the rest of the park. All such attractions will be mentioned on the Disney park website and in your guide map.
