Hi Nicol. The warmest welcome to planDisney, friend.
I'm sorry to say that at the moment, there is no option available for a partial-day ticket. That said, I have a recommendation that might interest you. On some evenings throughout the year, select Walt Disney World Parks host After Hours Events. These separately ticketed events have an added bonus, too! You can typically enjoy quieter queues at the Parks and indulge in some unique and delicious treats.
These events are available on specific nights until July at
Disney's Hollywood Studios,
Magic Kingdom Park, and
EPCOT. You can enjoy a complete experience by staying at your chosen Park until approximately 1am. Also, you can start your fun early by entering the Park at 7pm, three hours before the official beginning of the event at 10pm.
All available tickets are listed
online, but should you need even more ideas for fun and exciting activities around Walt Disney World without entering a Theme Park at all, planDisney created a podcast about '
Beyond the Theme Parks' that offers a wealth of information.
Nicol, I'm sorry that this may not be the information you wished for, but I hope I was able to help find a pixie-dusted alternative! If you have any further questions, please return to planDisney.
