I'm flying out from Heathrow terminal 5, but returning to terminal 2 (different airlines for outward and return due to available times of flights).
I plan to park in the long stay car park for terminal 5.
When I arrive back in terminal 2, is there a shuttle bus that will get me directly to the T5 long-stay car park? E.g., is there a bus service that does a "circular" service stopping at all the various car parks on the perimeter road?
Or should I use the shuttle train to go from T2 to T5, and then just get the regular car park bus from there?
