Yes, Oyster cards can be purchased at Heathrow - you need one each.
Unless you're interested in the 2-4-1 deals that are only accessible by having a ticket purchased at a National Rail, not Tube ticket office - and there is no National Rail station at the airport.
If you are - there are two threads on the top-right of this page that can explain more.
You can take the tube from Heathrow to Embankment via the Piccadilly and District lines, which takes a little under an hour. Off-peak fare on Oyster is £3.10 per person, or if you decide you want the 2-4-1 deals mentioned in post #1 and you therefore don't want to buy an Oyster card, you can buy single tickets for £6 each.
Alternatively, you can look at booking a car service - Blackberry Cars are one of the companies that are well reviewed on TA and they can give you a quote via their website. Depending on time of day, expect around an hour for the road journey. If you don't want to take the tube, a pre-booked car is definitely the way to go as picking up a black cab at the airport will be very expensive.
If you can give more detail on when you will arrive (date and time) you can get more precise information.
Thanks for the info. We will be arriving London on a Sunday morning and leaving on Friday afternoon. We will be using the tube in London so I guess buying Oyster cards sounds like a plan. Just want to make sure we need to buy one card per person. Is the tube from airport to embarkment station pretty straight forward? Some ppl also suggest using the Heathrow Express (is this a train or bus)?
<>If by taxi, about how much does it cost? <>
To answer this question, a black taxi from the rank at Heathrow would cost between £70 and £100 most likely.
As said above, booking a car service would be much more economical, probably £30-£45.
What is the date and time you are arriving? That could change the recommendation (e.g. the tube does not operate 24x7 and does not operate on Christmas day) and the estimated cost.
Some ppl also suggest using the Heathrow Express (is this a train or bus)?
Tube - Get on at Heathrow, the Piccadilly Line, and stay on until Hammersmith, then get off and cross to the opposite platform and get on a District Line tube heading Eastward towards Upminster - this means there are no stairs to contend with. Stay on until Embankment.
I'll let you plan your route from Embankment to the hotel with Walk It:
Yes the tube is straightforward. You each need an Oyster card (but as mentioned if you are interested in the 2for1's this may not apply
If you're splashing on the Corinthia I would book a car service at least on arrival. Should be around £35.Edited: 2:07 pm, September 23, 2015
