Most first time visitors to London don't have a grasp of the physical geography. One of my revelations was to find that Leicester Square and Picadilly Circus tube stations are about 200 metres apart. Much quicker to walk than to take the tube!

The Queen's residence

The Thames is a river which runs through London

Kew now has a section for young children called 'Climbers and Creepers,' where they can run in, out and around large botanically themed apparatus-it's free once adults have paid admission into Kew. Kew puts on art, craft and gardening activities for the children there too, although it is best to check exactly when they are scheduled for!

lovely mexican food at Wahaca in covent garden - it's cheap and really tastey. The MSC shimp salad is mv favorite. You can't book, and queues can be long. They have a waiting list so pop in, put your name down, then come back an hour or so later and your table will be ready.

Try the light bar at the St. Martins Lane hotel or Rockwell at the trafalgar! Both very good!

Remember that you can have all 4 seasons in one day in the UK so be prepared with adequate clothing

There are a number of river boats on the Thames - including the Thames Clipper which is a commuter service. Very comfortable and a great way to see London from another perspective

Went to The O2 for the Super Cross championships. The venue was amazing. Would definitely go back again.
