London Transportation

If you're staying for four days it will probably be cheaper to get an Oyster card and charge it with pay as you go money rather than getting a pass. Note that the Oyster covers travel from Heathrow to central London by the Piccadilly Line underground but not the Heathrow Express or Heathrow Connect trains to London Paddington, which will be more convenient for you as trains to Marlow leave from there. If you're staying in Marlow, though, that is not covered by the Oyster card range. You need to buy individual train tickets and if you're travelling from Marlow to London and back every day that might get pricey. Windsor is also not covered by the Oyster area.

Thanks for the info. We're only staying in Marlow 1 ni then we'll be staying in London for 2 ni. I'm assuming the Oyster pass is easy to obtain once we get to London. So it seems that we won't need to purchase any of these tickets before we leave other then the Chunnel for Eurostar. Is that correct?

Yes, that's correct. None of the other places you mention are far enough out to need pre-booking.

Buy your Eurostar ticket on-line as soon as possible for the best price. www.seat61.com offers ticket-buying strategies. One small tip: "Chunnel" is an outdated nickname that can make Europeans squirm.

Thanks so much for the replies. And thanks Southam for the heads-up on the termonology. I'll definitely remember that!!!

Buy the eurostar ticket ASAP. I bought mine a few weeks ago for a trip in June and have noticed the prices have already gone up.
