Here are good choices for business travellers who need quick access to Changi Airport — I’ve noted which properties run an airport shuttle vs. those that are directly connected/walkable (often faster than waiting for a shuttle). Shuttle schedules and policies can change, so I included official pages you can check or call before booking.

• Village Hotel Changi (Far East Hospitality) — free scheduled round‑trip airport shuttle to Terminals 1–3; business centre and meeting rooms, 20–25 minute drive to the airport if by road. (Confirmed shuttle info on the hotel site). (fareasthospitality.com)

• Aerotel Singapore (Transit hotel, Terminal 1) — airside transit hotel open 24/7 (no need for a shuttle — it’s located inside T1 departure/transit area). Good for very short layovers or business travellers who must stay inside the transit area. (changiairport.com)

• YOTELAIR (Jewel Changi) — landside short‑stay hotel inside Jewel Changi (level 4); walkable access to Terminals 1
