You'll be fine if arriving via WDW transportation (bus/monorail/boat). If arriving by car, expect to get turned away without a dining reservation; reports are hit-or-miss about mobile orders.
And keep in mind, holiday decorations are going to be much more limited than previous years. No gingerbread displays at any resorts this season. Only trees will be up.
