London for 4 days

are there must see sights in the world's number one city??? you're kidding right?

We don't have kids but did a few 'kid-centric' things in London - the Science Museum looks like it would be a blast for kids - lots of interactive things to do. The other was the Golden Hinde - a ship moored over by Southwark Cathedral - the guy doing the tour made it very interactive for the kids...the ones on the tour seemed to enjoy it.

We are going this summer.. our kids are a little older - 9 and 12 . Here is what is on our list

• Tower of London (already booked)
• Harry Potter studio tour (already booked)
• Star Wars exhibit at the O2
• Hop on and off bus.. we do these in every city we visit
• Westminster Abbey
• St Paul's Cathedral
• Kensington Palace and playground ( already booked)
• Changing of the guard/changing of lifeguard
• London eye ( possibly)
• Hampton Court Palace ( booking shortly)
• Big Ben and parliament buildings
• Hamley's toy store
• a number of parks: Chrystal palace, Queen's Olympic park and potential aquatics centre,

Maybe:
- Thames river cruise
- going to see a Play

Narrowboat from Little Venice. End in Zoo or Camden Market.

We're going to London in July. Re: Harry Potter tour-- I know it's a studio tour, not a theme park

Also, for younger children, I came across a "treasure hunt at the British Museum" that might be fun for your family. It does have a cost, but the museum admission itself is free. If you don't think your kids would put up with walking around it without some incentives, this might be a good option; there's so much to see in the museum! It's mostly artifacts from all around the world (as opposed to paintings/portraits).

We had done the Thames river cruise to Greenwich. There, we visited the observatory. Did it on the weekend when the Greenwich Market was running. Our kids enjoyed it.

As a father of two teenagers that has travelled with them extensively, I'm guessing your kids will enjoy seeing Big Ben and the Parliament building, Westminster Abbey because of all the kings and queens buried there, riding on the London Eye, the Egyptian and Greek stuff at the British Museum, the changing of the guard at Buckingham Palace, and going to the toy department at Herrods.
