The opening times at Walt Disney World varies depending on each individual park and the time of year. Generally, the parks open between 8:00 am and 9:00 am and close between 9:00 pm and midnight. However, there are some exceptions, such as during special events or holidays. It's always a good idea to check the park's official website for the most up-to-date information on opening times. You can also download the My Disney Experience app, which will give you real-time information on wait times, show schedules, and more. One tip is to arrive at the park early, as this is often the least busy time of day. You'll be able to enjoy more attractions with shorter lines and avoid the midday crowds. If you are staying at a Walt Disney World resort, you can enjoy early access (usually about 30 minutes extra) before the park opens to non-Disney resort guests. Don't forget to plan your visit accordingly to make the most of your magical day at the happiest place on earth!
