For early morning or midday on December 31, hotel spas fit. Kee Spa opens at 09:00 with private rooms and nine couple rooms, and Ryn Spa at Grand Mercure runs to 20:00 with a 15-minute refresh break, foot cleansing and tea time, built into every program.
For a party of three to seven, Sansabai Massage 1 is the simplest. Four shared rooms with three, four, six and seven beds and four couple rooms let everyone take treatment together, and it is near Jungceylon for pairing with shopping. No program includes a shower.
For the evening before the countdown, three venues in central Patong share a midnight close. Second Street is a day spa, M Social sits inside a hotel, and Makkha Calm on Third Street gives a free shower with oil programs.
If Patong crowds put you off, look at Let's Relax Karon, which suits guests staying on the Karon side. To be treated after midnight, Lyn Spa and Massage stays open until 4 a.m., about seven minutes by car from Patong Beach, so factor in New Year's night traffic.
Before booking, confirm the last booking time, shower rules and whether a room is guaranteed. Holiday hours can change, so use the current product details as the reference.
