San Diego is the better fit within this comparison when you want the coast and city attractions to carry the holiday, with a festival as one addition. December Nights offers a free event in Balboa Park on December 4–5, but food, shopping and transport remain separate costs. Plan the return before arriving, especially if attending a major evening event with children. A later Christmas-week trip needs a different confirmed seasonal activity or can simply be a city-and-coast stay.

December Nights takes place December 4–5, 2026. Visitors arriving later should choose San Diego for the broader trip rather than assume this named festival continues all month. Give the park outing its own transport plan. If you are also visiting Anaheim, keep the intercity transfer separate from the festival evening.

Combining Anaheim and San Diego can work on a longer holiday. Treat the transfer as a real component of the itinerary, including luggage, check-out, check-in and traffic uncertainty. Do not put a prepaid evening activity immediately after the move. If you have only a few nights, one base usually gives you more usable leisure time than an ambitious list spread across Southern California.
