Hey there Ron. Welcome to planDisney.
The minute I read "add on another day" I knew you were my kinda guy. It is truly magical when my schedule opens up after I have made plans to visit Mickey and the rest of the Fab Five allowing me to spend extra time at my home away from home.
Because you use the word "package" I am not sure if you mean adding an additional theme park admission or an additional
theme park admission and an additional
Disney Resorts Collection hotel day.
If you want to know about adding another theme park entry then the answer is a resounding "YES!" You need to add the day before your last theme park entry by visiting a ticket window, Guest Services location, or the
Disney Ticket Center at Disney Springs. You will pay the price difference between a 4-Day and 5-Day base tickets so it will be more expensive in total but less expensive per day.
If it is adding a hotel day and a ticket day then it will depend on hotel availability and current offer but you should still be able to add a ticket day.
Ron, I hope May 2025 is a pixie-dusted adventure. Please feel free to reach back out to
planDisney for any more Disney vacation planning advice.
Enjoy making many Magical Memories.
