Our pick

Hilton Garden Inn London Heathrow Terminals 2 and 3

Room, typical: £170–£270
Transfer: £0
Typical total: £170–£270

Who it suits: Families staying a full night before a morning flight.
Why we would choose it: A family room with two king beds and room to spread out, reached from Terminal 3 through the underpass in eight to ten minutes, under cover.
The compromise: A longer walk with children and bags than staying inside the terminal.
Worth paying more?: Yes for a full night. The extra space matters more than the extra few minutes.
