Hi, I have to travel within London on Wednesday. Part of my journey will require using the London Underground. I believe I am best to purchase one of those paper tickets that allow unlimited travel for that day. I will only require zone 1 + 2 (may travel out to zone 2 at the end of the day to pass some time whilst waiting for my train home; I've intentionally selected a later train to enable this). Normally I purchase the ticket on the day from one of the ticketing offices, however this has typically been when visiting London for leisure and hence no rush. On Wednesday time will be more important. I need to get from St Pancras/King's Cross (arriving at 0809) to Paddington by 0857. Normally I'd have thought this would be bags of time, but having never visited London during these hours I thought it would be best to factor in a bit of a buffer. Ideally I'd like to purchase a paper ticket for the London Underground online - A day pass (peak) for zone 1 + 2. Is this possible? I would like to avoid the Oyster Card option as I do not visit London often enough. Can anybody advise if this is possible, and if so from where? If this is not possible, can anybody confirm if there should be sufficient time for me to visit a ticketing office at St Pancras/King's Cross during the hours stated to make the connections as above? Thank you!
