Hey there, Marbella!
So I was in a similar situation with the Disney Park Pass system just recently, and I think that I can offer you a bit of insight.
We planned our trip and at the very last moment we had an extra addition who did not have a
theme park ticket or a
Disney Park Pass system reservation.
I was able to snag a last-minute reservation by trying over and over and over again. You see, the Disney Park Pass system is
updated in real-time. So as people cancel or change their plans, I was able to pick up an extra pass.
I will tell you that there is no guarantee with this method, and I was not able to get the reservations until the day before, which would not give you a lot of time to plan.
If there is a different park that has availability for that day, you can go ahead and switch your whole group to that park and then add the
Park Hopper Option, hopping over to your originally scheduled park after 2:00. This plan may be the best of both worlds, as you get to experience the magic of two different parks in one day! This was my family's back-up plan if we were not able to get an extra reservation for our desired park.
If you are unable to change your plans to a different park, I would recommend that you see if it would be at all possible to switch your vacation around a bit and visit on a day with availability.
I know that this may not have been the answer that you are looking for, but I hope it gave you a bit of clarity. Keep trying and do not give up!
See you real soon!
