There's quite a comprehensive Hoppa timetable posted at the bus stops around LHR, detailing precisely when the schedules increase/decrease for each specific hotel. (i.e. about 5pm the one to the Crwone Plaza drops in frequency quite sharply).

I've searched the BAA website and whenever it talks about the Hoppa, it points you towards National Express. However their site has no details at all.

Anyone know where I might find one of these timetables (short of "on a wall at LHR")

(Alternatively, if anyone can tell me which hotels have the more frequent service from the airport around 9pm....)

Thanks

Tony
