Reply To: Heathrow hotels – best option?

[John]

Heathrow should really be thought of as 3 separate airports. The only actual link is that you and any interlined checked luggage can transit between flights between those 3 “airports” without entering the UK.

(Advanced users can use T3 lounges with a T5 BP at the cost of considerable hassle and time.)

Actually if Paddington hotel (e.g. Hilton) + HEx round trip is cheaper than T5 Sofitel that would be just as convenient for T3.
