Friday I'm going to London (Thursday at 22.00 to be precise) by buss, it's a trip organized by my school, we are one day in London and then go back home again so it stays affordable. Now I was thinking, one day in London, what should I visit? Does anyone have suggestions or maybe things I should watch out for etc. etc.? (BTW, I only stay in Zone 1 and 2 because otherwise it will be too far away. Zone 1 and 2 are the zones where you can find the Tower Bridge, Big Ben, British Museum etc. If you don't get it, then don't mention it. )
