Driving and parking in London is a nightmare so I'd recommend a park and ride system into the centre.

I agree about the museums, the Natural History Museum being my very favourite. It is a very quintessentially British museum.

There are no words to describe the greatness of Harrods , and Hamleys the toy shop is a wonderful place for kids to visit.

If you get nice weather, take an open-top bus tour! That's a really easy way to see everything, and if you see somewhere you'd like to visit, all you have to do is hop off.

It's a shame you aren't going later in the year, since I'll be going to university down there from September. Would have been nice to see a PTer!

Have a great time, whatever happens, you will not be bored in London!

One word of advice about the tubes - keep your belongings safe and zipped up at all times in the stations. A large handbag or satchel that you can clutch under your arm as well as wear a shoulder strap is good, whereas backpacks can easily be slashed and emptied without you even knowing it. Commuters know exactly where they're going in London and unfortunately the tourists stick out like a sore thumb to the pickpockets. I've never known anyone have a serious problem but it is sadly a thriving part of the city scene. Awareness is key to avoiding such mishaps.
