I had a difficult time in London so here are the tricks
– for Airport Hotels (Hoppa Bus – 5 GBP per person at the driver, or 9 GBP 2 ways, valid 2 month)
search for your terminal and hotel here (there are a lot of pages)
search for the bus station location on the last page on this link (timetable also included)
– for London Central Hotels get the train
See all options on this link
