Hi Taylor!
Welcome to planDisney!
Thank you for sending in this question - with this ever-evolving situation, transport options are changing all the time, and I'm happy to clarify this for you, as of today.
Disney buses have continued to run throughout the re-opening of Walt Disney World Resort, and are currently transporting guests from all Disney Resort hotels to all four theme parks, and Disney Springs. Buses start operating around 45 minutes prior to park opening, and run throughout the day until approximately an hour after closing.
Park opening hours can be seen here on the calendar.
Exciting news was announced last week that starting January 1st, 2021, park hopping returns to Walt Disney World Resort (for guests with admission tickets including the park hopper option, and will always be subject to the park's capacity limitations). Guests will still need to make a
Disney Park Pass reservation for entry to their first choice of park for each day, and park hopping will commence from 2pm each day.
Bus transport between parks is not available during 2020, but park-to-park transportation is due to return in 2021 after park hopping returns, and will commence daily just before the start of the park hopper hours at 2.00pm (subject to change).
If you are visiting in 2020, you would need to take a bus from Disney's Animal Kingdom Theme Park to any Disney Resort hotel, and then transfer to another bus for EPCOT. To save you time, you might prefer to take a taxi direct from park to park.
Please come back and visit us if you have any further questions. We will be happy to help you plan your magical vacation!
