How to go from Holiday Inn T4 Heathrow to T3
Hey guys, sorry for bothering with a question that must be pretty simple, but I’ve done some research and was not able to figure it out, so here it goes.
I’m staying at Holiday Inn T4 in Heathrow and have to go at around 8 am to T3, from my research the best way is to catch the Hoppa bus to get there, but I would like to know if it is possible to simply walk to T4 and then catch some kind of train that takes me from T4 to T3?
