I was going to be looking for this very piece of Info, soon myself ^

I’ll be staying at a LHR hotel the night before a LHR-IAD trip in a few weeks time & was going to need to find out how to get from Hotel to T5 the morning of my flight.

Never did a pre flight overnight at LHR, always have connected in on the morning of my flight, so this will be a voyage into the unknown for me.

Is the “Hoppa” the best way to go ?? Or is that really dependant on which hotel ??

I’m currently looking at the Marriott, but wonder if the T4 Hilton would be better, as at least I’d be on airport property.

But then how does one get from T4 to T5 ???

Edited to add........

Excellent link there TBS ^
