According to sources familiar with the plans, Disney is considering expanding the Park Pass reservation system at Walt Disney World to include park skipping.
Currently, park hopping is permitted at 2:00 p.m. without a reservation, provided the customer has a valid ticket and a reservation for the first park of the day.
In the plans under consideration, a guest could make a reservation for the secondary parks at other times and not be limited to 2 p.m.
The change would allow customers greater flexibility in planning their trip, but would further increase the already complicated and frustrating process of securing park reservations before a visit.

Sources also suggest that the ability to make multiple daily Park Pass reservations may be tied to different ticket tiers or sold as an optional upgrade.
The Disney Park Pass reservation system was introduced when the parks reopened after the COVID-19 shutdown to limit attendance due to capacity restrictions.

Disney CEO Bob Chapek frequently mentions the Park Pass system as a huge benefit to the company by allowing tight control of operating costs and attendance management. Originally thought of as a temporary measure, the Park Pass reservation system is now permanent.
Note that Disney has not announced any changes to the Park Pass system and plans change frequently.
