While no park-to-park transportation has currently been available, Disney plans to resume this form of transportation in 2021 to make park hopping a breeze!
As shared on the Walt Disney World website:
Complimentary Resort Transportation: Transportation is operating with physical distancing measures in place, including in the load zones and queues, as well as aboard buses, monorails and watercraft boats. Face coverings are required at all times while boarding and using Walt Disney World Transportation. We have also added physical barriers in select places where it is difficult to maintain strict physical distancing guidelines, such as partitions inside our buses and monorails.
At this time, Guests may only visit one park per day. With this in mind, complimentary transportation between theme parks is temporarily unavailable. This includes temporarily suspending monorail service between the Transportation & Ticket Center and EPCOT.
Park-to-park transportation is planned to resume in 2021, with operations beginning each day shortly prior to the start of Park Hopper hours.
