Christmas and New Year in Bangkok

Bangkok in December is as good as the weather gets. This is the cool season: daytime temperatures that are warm rather than punishing, low humidity by local standards, very little rain, and evenings that are genuinely pleasant to be outside in.

That matters more than it sounds, because it changes what a day can hold. In April you plan around the heat and retreat indoors at midday. In December you can walk a market, cross a park and sit outside for dinner in the same day without it costing you anything.

It also means the pool is a nice extra rather than a survival tool, which affects which hotel makes sense. In December, a hotel without a pool is a much smaller compromise than the same hotel in April.

Bangkok's malls take Christmas decoration extremely seriously and treat it as competitive. From late November the forecourts fill with installations that are less window display than small theme park, and they stay up through New Year.

The Em District on Sukhumvit is the easy one if you are staying on that side: Emporium, EmQuartier and EmSphere are within a few hundred metres of each other, all decorated, all connected by skywalk. ICONSIAM on the river is the most spectacular of them, and it is worth the trip across town on a night when you are not tired.

Go on a weeknight if you can. Weekend evenings in December bring out the entire city with phones raised, and the same display at eight on a Tuesday is a completely different experience.

The 25th is a normal working day here. The Thai public holidays in December are the 5th, which is the late King Bhumibol's birthday and also Father's Day, and the 10th, Constitution Day. Then the 31st and the 1st of January close the year.

This has a practical upside. Christmas Day itself is one of the easier days of the season to do something popular, because the crowds at the Grand Palace or a big temple are made up of visitors rather than visitors plus the entire local population. If you want a calm Christmas morning at a major sight, you can have one.

The pressure lands on the 31st instead, and to a lesser extent the 5th and 10th. Those are the days to keep local and avoid crossing the city.

The 31st is the big night. The riverside around ICONSIAM puts on the largest fireworks display, CentralWorld hosts the main countdown crowd in the centre of town, and every rooftop bar in the city is booked and priced accordingly.

The part people get wrong is the journey home. Enormous numbers of people finish at the same moment in the same few places. Taxis become scarce and expensive, roads near the river and Ratchaprasong close or crawl, and the trains, which normally stop around midnight, usually run extended hours on New Year's Eve specifically, though you should confirm the timings closer to the date.

The simplest fix is to stay on the BTS corridor and pick a countdown you can reach by train. Being able to walk to a station and be home in fifteen minutes is worth more on that one night than any view you paid for.

The holiday fortnight is the least forgiving stretch of the year to book late, and hotels do not sell out evenly. Twins, connecting rooms, family configurations and quiet floors disappear well before a property looks full on a booking calendar.

Families booking two rooms together are the real constraint rather than total occupancy. If you need two rooms on the same floor, or a triple, or a cot, that requirement is the thing to secure early: the rate will not improve by waiting and the configuration will simply stop being available.

Put the details in the booking notes: how many rooms, whether you want them adjacent, arrival time, and anything about the party the desk should know. Booking direct puts that note in front of the team who will actually check you in.

Arawana Regency Park Sukhumvit is the pick if you are travelling as a family or want somewhere to eat without going out, which matters more when the streets are at their busiest. It also has the Family and Triple rooms that go earliest.

Arawana Express Sukhumvit 22 on the same soi keeps the rate down if you are out most of the day, and in December, when a pool is a bonus rather than a necessity, that trade is much easier to make than it would be in April. The full comparison is in Regency Park or Express 22.

If your stay runs across Christmas and New Year both, look at Arawana Regency Park Sukhumvit instead. Past about a week the kitchenette starts earning its keep, particularly when restaurants are running holiday menus at holiday prices and you would occasionally rather not.

Hotels and international restaurants across Bangkok run Christmas menus, and the good ones book out well in advance. If a traditional dinner matters to your party, reserve it at the same time you book the room rather than in the week before.

The alternative is to lean into where you are. A very good Thai dinner on the 25th, somewhere with tables outside in twenty-six degrees, is a better memory than a mediocre roast served in a city that does not do roasts especially well. Most guests who try this once do it again.

For a large group, book anything at all rather than walking out hopefully. December evenings fill the popular places every night of the week, not only on the 25th.
