Big Ben, London Bridge, Tower of London and the original Madame Tusards are just some of the awesome sites you can see while in London.

I highly recommend Oxford Street for shopping. They have the coolest stores for pretty good prices.

If you want to do the "touristy" thing, then you could always get on a double decker bus, but it's much cooler to set out on foot with your family and a map. Also, you'll have a lot more fun experiencing things first hand.

London's an awesome city and if you're lucky, you may even get a glimpse of Prince William while by the royal palace.
