For daytime on December 31, Shang Palace at Shangri-La opens at 11:30. You can choose between the weekday dim sum buffet and a six-course set, which suits a plan that leaves the evening free. A New Year surcharge may apply, so check the fare on the listing.
After dark the choice splits between the river and the riverbank. The Manohra cruise sails at 17:30 on a small royal barge, while Sala Rim Naam starts at 19:00 and runs to 23:00 with a traditional dance and a course. Both have dress codes, and Manohra wants you there 30 minutes before sailing.
Above the city, Vertigo (61st floor, until 22:30), Seen (DJ show, to 25:00), Spectrum (live band, to 25:00) and Red Sky (live jazz, to 25:00) differ in character. For a course dinner that ends early, Vertigo; to keep the mood going close to midnight, the other three.
On January 1 afternoon, afternoon tea at Author's Lounge, Mandarin Oriental, runs 12:00 to 18:30. It requires one set per person and allows two hours, so slot it in as the first plan after a late morning.
Before booking, confirm the New Year surcharge, the dress code and the late-arrival rules on each listing. Hours and menus can change with hotel and restaurant circumstances.
