I'm a bit of an environmentalist at the best of times, but pretty much anyone can agree that driving into London is not the best way to get there. From the traffic, to the congestion charge, to the expensive parking.

I've always been driving to Thornhill Park and Ride near Oxford, and taking that into London, but at about £35 on the day, I think I could do better. I would take the train, but that's about double the price from where I am!

What do you guys do when you have to go to London? Do you have any secrets for getting there cheaply? This question will probably vary depending on where you guys are in the UK, but I think it'd be interesting to hear a variety of strategies anyway!
