I want to book a trip to London from York on the 23/06/2015 after 07.00 and return to York after 18.00 the next day. I also want a paper Travelcard zone 1 to 4 for both days. Is it possible to book it into 1 ticket or do I have to buy the 2 Travelcards separately. If I put in York to London zone U1234 does that mean unlimited trips on the Travelcard all day or is it only 1 trip. Thanks for the help in advance !!!
