You might not have many options to choose from on property since the 60 day dining mark already passed for Christmas Eve/Day. We've had enjoyable Christmas Eve meals at Citrico's and Hoop Dee Doo (not open yet). We usually do Christmas day in MK. If you have to travel around Disney that day you may want to pick a deluxe resort with great holiday theming or activities to make it worth the transportation nightmare you will probably endure. Otherwise, I would consider eating dinner somewhere either in or near your resort to minimize traffic headaches. In my experience, you want to limit your travel as much as possible on Christmas Eve/Day (and that following week) at Disney as the roads and transportation are packed. Disney already does not have a large pool of bus drivers due to the labor shortage, so even Disney transportation will be a mess those days (worse than usual if I had to predict). Uber surge pricing is through the roof on holidays and drivers are hard to come by. I would avoid Disney Springs on the holiday unless you are going right at opening. If you are driving, it is highly likely the garages will fill to capacity at some point those days.
