Welcome to planDisney, Lashonte!
I am so happy that you stopped by with this great question!
Lashonte, if there are no more
Disney Park Pass system reservations for a particular day, you will not be able to purchase a one-day admission ticket for that theme park.
When I was in this situation a few weeks ago, I purchased a theme park ticket for a different park. I then kept checking the
Disney Park Pass system Availability Calendar to see if any dates opened up. Once a date opened, I was able to transfer the ticket from one park to another to join the rest of our party.
Now, Lashonte, this method is not guaranteed at all, so if you need to have more concrete plans I suggest that you move your entire party to a park that has open reservations. You can then add on the
Park Hopper Option. After 2:00 your entire party can head on over to your desired theme park, as long as it has not reached capacity.
I hope that this helped, Lashonte! Please come back here if we can answer any questions to help make your stay magical.
See you real soon!
