Hello there Elissa, welcome to planDisney!
Thank you for your service, and I'm so glad that you're able to take advantage of the
special theme park ticket offer for eligible US Military Members! I chatted with a Cast Member, and I have good news. You can use your last day on December 15 and book a theme park reservation for that day! You will need a corresponding
theme park reservation for each day that you plan on visiting the parks, you can reference the
theme park reservation availability calendar as well for the dates you plan to visit.
If you're in need of a place to stay, I would explore the
great rates available for eligible US Military Members at Disneyland Resort Hotels! All of the
Disneyland Resort Hotels are magical in their own way, and you truly cannot go wrong with any of them, it truly comes down to your family's personal preference.
I also highly recommend checking out the Flag Retreat ceremony that takes place at
Disneyland Park each day on Main Street, U.S.A. Guests and Cast Members will pause to honor those who have served, and it's such a wonderful tribute. You find the time that it will take place in the
Entertainment Schedule under Atmosphere Entertainment.
I hope this information is helpful to finalize those last details for your trip! Elissa, if we can help with anything else,
please do not hesitate to come back to planDisney!
Have a magical day,
Melissa
