Leave next week and still a few more clarifications I would like please. If we take the Heathrow Express from Heathrow to Paddington and then a train out to Bath do I need to reserve those ahead of time or can I just buy them before or on board? We are supposed to be arriving about 6:00 am. at Heathrow.
For the train out to Windsor we should be able to buy tickets at Paddington before hopping on board, correct?
We will definitely be getting the Oyster card. Any other tips or tricks would be awesome and thanks!
