Can anyone point me in the right direction, going to london for four days with the wife and daughter, whats the best deal for the underground. Is it buying a a single day pass for us all or do i have any other options. Thanks in anticipation.
It depends on where you're going to stay in London, and how much you're going to travel around! I'm not sure if there are some special offers available, but getting an Oyster card is the easiest (and probably the cheapest) way to travel. The card itself costs about £3, then you can "load" money on it and you just show the card on the underground gates. No matter how much you travel it'll never cost you more than a one-day travelcard would, so I think it's the best option.
RE: Think kids are free on the underground nt Under-5s Children under five can travel free at any time on the Tube, DLR, buses and trams as long as they are accompanied by an adult with a valid ticket. from http://www.londontoolkit.com/briefing/underground.htm
