How do I get from Heathrow Airport main bus station to St Pancras International Station on sun 24th Feb @5am?

We will be arriving in Heathrow by bus at approx 5am on the 24th feb. We then need to get to The new St Pancras Station for the Eurostar at 8am. We've never been to london before and need to know what tube to catch or what other ways there are? Help!! Its Our honeymoon and if i mess this up im a dead man

The best and stress free way to do this is to get the Heathrow Express. Follow signs to rail and then buy your tickets from the machine or on the train itself. The trains are at 05:08 05:23 05:53 (and every 15 minutes after) and take 15 minutes to get to London Paddington station. I would then go to the right hand side of the station to the taxi rank and take a black cab to St. Pancras. You could also take the Hammersmith and City line from the underground station at Paddington to Kings Cross/St. Pancras (takes 16 minutes). Much more sensible than doing the whole thing on the underground which can take forever. This way you know you'll be there with plenty of time to spare and have breakfast before your train.

Ignore the other answer which says it goes to Victoria (they're thinking of the GATWICK Express!).

National Rail is good, but only for overground trains, not bus or tube or walking.

jump onto the underground at heathrow which is the piccadilly line. get of 24 stations later at kings cross station. walk out the main entrance and take a right. then you take the first right and walk to the end and st pancreas is there on your left. there is no direct tunnel from kings cross to st pancreas at the moment as they are just finishing building it. there might be a shorter tempory tunnel route though

Can I be brutally frank? To do that journey at that time of the day, by public transport, will involve a number of changes and very possibly a fair bit of walking. As it's your honeymoon and, as you say, you're a dead man if it goes wrong can I strongly suggest looking at the option of taking a taxi; more expensive, but less stressful & will get you there in time and comfort.

I would get Heathrow Express to Paddington (15-18 minutes) then a cab to Kings Cross St Pancras, as I believe there is engineering works on circle/metropolitan/bakerloo underground lines.

If no engineering works just get the tube between the stops

You probably can take the Heathrow Express that will take you to Victoria I know that but not sure if it runs that early?? Check with Heathrow.
