Things to see in London

Ok here's my must-see list for London (in no particular order):

- Big Ben

- Westminster Abbey










- Tower Bridge

- Buckingham Palace - change of the guards

- Tower of London

- The National Gallery

- British Museum

- The London Eye ?* (not sure about this yet)

- The London Underground

- Trafalgar square and

- Picadilly Circus

Optional: Stratford-upon-Avon - Shakespeare's birthplace

*From some of the things I've read, the London Eye is overpriced, so might just visit the outside

I've also read that it would be cheaper to get a London Pass and an Underground Pass to pay less for entry to attractions as well as skipping long queues.
