Hi Staci, welcome to planDisney!
That is an amazing Christmas present, your family will be so excited!
Normally
theme park reservations can be booked up to 120 days in advance. However, currently, it looks like reservations are only available up to February 16, 2023. I spoke with a Cast Member about this, and they stated that while the 120-day rule is what typically takes place, it's not guaranteed. My recommendation is to keep an eye on the
Theme Park Reservation Availability Calendar. Hopefully, reservations will become available to book past February 16, 2023 soon!
And speaking of reservations,
dining reservations can be booked up to 60 days in advance, so your booking window will open up in January 2023. I would definitely mark that in your calendar, as securing dining reservations for large parties can be tough.
Please visit us again if you have any further questions!
See ya real soon!
