At Changi, "airport hotel" can mean two different things, and the line between them is immigration.
Airside: no immigration
Changi Transit Hotel is at T1 (Level 3, near gate D40) and T3 (Level 3, beside the movie theatre). Ambassador Transit Hotel is at T2 (Level 3, Departure Transit Hall South). All three are in the secure area, open 24 hours, and sold in blocks of hours. A third-party guide gives six-hour rates of about S$160 for the T1 Standard room (bathroom outside) and about S$260 for a Deluxe, and about S$317 to S$355 for twelve hours. Only cabin bags go into the rooms, and you need your passport and an onward boarding pass.
If you arrive from the city and want a room, you have to check in and clear departure immigration first.
Landside: you enter Singapore
YOTELAIR is on Level 4 of Jewel, in the public area. A transit passenger must clear arrival immigration to reach Jewel, so it is not an airside nap. It sells day cabins from four hours between 06:00 and 22:00. Crowne Plaza stands beside T3, outside immigration.
The T2 change
From 3 November 2026 Ambassador Transit Hotel becomes Changi Transit Hotel T2. Stays from that date book through changitransithotel.com. We will update this page once rates for the new hotel are published.
Do you need one?
Under about five hours, a free rest area (reclining chairs in each terminal) or a pay-per-use shower is cheaper. A transit hotel earns its price on a connection of six hours or more, particularly overnight.
