Park Reservation System Means No Park Hopping With Ultimate Tickets
Due to the park changes thanks to the coronavirus pandemic, you will only be able to book one park a day, with no park hopping.
For those still planning to go to Walt Disney World in 2020, the 7, 14, and 21 day Ultimate Tickets include "unlimited access to all SIX Disney Parks", but that's not something Disney can offer in the first stages of reopening.
According to an email Virgin sent out to its' customers, the park hopping "unlimited access" no longer applies because of the changes made at the parks due to the coronavirus pandemic.
You can request one park a day. As customers won’t need to hop between parks, the hopper service is currently suspended
Won't need is a poor choice of words, because Virgin obviously don't understand my Disney needs. However, because of the new park reservation system, you are only allowed to make a reservation to visit one park per day. Which means park hopping is off the table until things slowly go back to normal.
