Around December 24 daylight is short, streets are dark by about 17:30, and the evening — lights, dinner reservations, the walk back — becomes the centre of the trip. That puts the distance from your last stop to the hotel door ahead of room size. A public bath, sauna or in-house restaurant is a practical filter in December rather than an extra. Free-cancellation deadlines differ by date, so open the plan for the exact night you want.
The subway takes roughly five minutes from Fukuoka Airport to Hakata and about ten to Tenjin, which lets you start the evening even on the short December days. Hakata favours shinkansen, JR and airport access; Tenjin and Nakasu favour Christmas lights, food stalls and evening walks.
The airport-to-centre ride is short enough to check in before dusk and begin the lights walk the same evening. A Hakata Station hotel keeps you close to the station-front illuminations; a Tenjin hotel suits walking between shops and restaurants and heading back within a stop or two by subway. Treat ten minutes on foot as the limit for the return on Christmas Eve, when taxi queues can run long. On departure day, work backwards from breakfast start time and airport transfer to set check-out.
