Hello Resort Hoppers! I am going to be at Disney very soon, and I had a question about something Jenna mentioned on the stream yesterday. She said that she had been at another park earlier, and then had park hopped to Hollywood Studios because she couldn't find an available ticket for that day. I know that you do not need a "ticket" for the park you hop to after 2pm, but I was wondering do you need any special ticket or to be an AP holder to park hop? To give some context, I am going to Animal Kingdom one day since MK and HS were completely full, and I didn't know with a normal, one day ticket if after 2pm I could hop over to MK from AK? It sounds too good to be true... Thanks for all of your help hoppers, see you in the group chat!

PS- Wishing you a speedy recovery Josh!!

You have to have a park hopper ticket in order to hop .

Hi, Angus.

Here is the latest official info:

How It Works
Guests who purchased a ticket or annual pass with the Park Hopper benefits will be able to visit more than one park per day, with some new modifications as part of our ongoing focus on health and safety. These modifications are designed to help us continue managing attendance in a way that fosters physical distancing.

We will set specific Park Hopper hours during which this option are available. Park Hopper hours will start at 2 PM each day and end at the park’s scheduled close time. Guests are now able to check the Park Hours calendar and the My Disney Experience app for the most up-to-date Park Hopper hours, as they could start earlier at a later date, depending on the day and park.
With the updated Park Hopper experience, Guests must make a Disney Park Pass reservation for the first park they plan to visit AND enter that first park prior to visiting another. At this time, a park reservation is not required after the first park, however, reservation requirements are subject to change.
Reservations for dining experiences, Droid Depot, Savi's Workshop and other pre-booked experiences do not guarantee access to a park, and Park Hopper availability may change daily. We recommend Guests book in-park dining and other experiences at the park where they have a Disney Park Pass reservation. Guests can make dining reservations or add their party to the walk-up list at select table-service restaurants via the My Disney Experience app after they enter the second park, subject to availability.
Please note that the ability to visit another park will be subject to the park’s capacity limitations. In the event that the Park Hopper option is unavailable at a theme park, Guests will be notified in real time via a push notification from the My Disney Experience app.

What I might infer from Jenna's comment is that a park that she had wished to park hop to was over-capacity...or...she had tried to book a straight up ticket to a park that day and was unable to because of overcrowding.
