I've been to London twice, one time for two weeks for business. I love London, its like New York, only European!!! I would suggest taking a ride on the London Eye, its the new ferris wheel( it was built for the millenium) and its over by parliment/big ben. Its huge and gives you a great view of the whole city!!!
Definetely see St. Pauls' church, its gorgeous and they do tours. Its the church that pricness diana got married at.
And of course go to Buckhingham palace and see the changing of the gurad.
