Heathrow tourist trap buses
So I slept in the Sheraton Heathrow hotel last night. It's a half-an-hour walk away from the airport, or a five minute bus drive.
If you go to any service desk and ask for the best way to get to the hotel, they'll offer you a ticket for the 'HotelHoppa' service, which will stop right in front of your hotel entrance, and costs £4 for a one-way trip (even though the bus sides declare a £4.5 charge)
However, if you take the regular "London United" bus service (which drives all over London, not just near the airport like the HotelHoppa service) then the same trip is completely free of charge. You may have to walk about a hundred yards more to reach your hotel, since the bus will stop at a regular bus stop rather than at the hotel entrance, but that's hardly a problem.
What a ripoff.
So, to clarify, don't take this bus:
Instead, take this bus:

Edinburgh airport has a dedicated bus running from the airport to the city center. That costs £4.50 for a single journey.
There are also buses from the local company, LRT, which cost £1.20 taking you from the airport to the city center and beyond. Sure they take a more circuitous route, but they go further and don't cost a fortune!
