So, let's say you have 9 hours spare. Are you flying from Heathrow or Gatwick?

If Gatwick, if you like I'll come and get you, and show you some of Sussex, the place I live, which is lovely and green and typically English. If Heathrow, then the centre is about an hour on the tube (do not get a cab, it will take longer and cost you around 200-250 bucks, tube will cost you 12 bucks).

Then, well, depends what you want...you could get a tourist bus thing and see all the big sites, you could go to a museum or two, you could get an amazing meal at one of the more famous places to eat, you could do some shopping, see a park or two...dunno what you like. The embankment is cool too, you'll get to see the London Eye, tate modern, national theatre (which is always cool cos the skateboarders and BMX folk all do their stuff around there).

Lots of choices...
