It looks as though I'll be spending a week in London, and while I'm there, I'd be interested in spending as much time out and about, walking as much as possible. I'll probably be operating from a base well away from the centre, so I'll be travelling every day in and out of the city.
Now... for those folks who do this sort of thing all the time... what's the best way of doing this? From a quick online search it looks as though I have two options... the Oyster Card... and the Travelcard. From what I understand, the Oyster Card has to be topped up with money, and every time it gets used, the journey cost is debited from the card, and works out cheaper than buying a ticket for each journey made. The Travelcard, on the other hand, has an option offering unlimited travel across all zones for seven days.
Assuming, for the sake of argument, that I was based on one side of London, but travelled every day into the centre, and most of the way out the other side, then back again later in the day... then which of those cards will offer the best deal?
Incidentally, I reckon the bulk of my journeys will be on the Tube network.
