Hi Matthew!
I’m so sorry to hear that your wife will have to leave your vacation a little bit early. Hopefully, you’ll be able to pack tons of magic into the beginning of your vacation that your wife will be able to enjoy with the rest of the family!
Walt Disney World Resort theme park tickets are non-refundable and non-transferable. So, unfortunately, once your wife has used the first three days of her 5-day theme park ticket, it cannot be transferred to somebody else to use the remaining two days. You can only reassign the ticket to someone else if none of the ticketed days have been used. So if you wish to reassign the 5-day ticket to somebody else before your trip and purchase your wife a new 3-day ticket, you would be able to use all of your ticketed days during your vacation.
Matthew, I recommend that you add
Memory Maker to your trip because it’s a great way to capture all of the magical moments you experience together. Plus, it's the perfect thing to allow your wife to view and enjoy the moments you experience after she must depart for home.
Please come back to see us if we can help you with any additional questions that you have as you continue planning your trip! T-T-F-N, ta ta for now!
