We set out to accomplish a lot on our first day in London. We started out late from where we were staying, 10am. It just took us a few hours to realise the following:
1. Buy an Oyster Card for local transportation. Children below 12 travel free. You can expect to spend about £8 to £10 in a day. Oyster card covers rail, tubes, trams, buses.

Caution: During peak time, the tube stations make you feel as if you are standing in Rajiv Chowk Metro Station.
2. Most attractions shut by 5:30pm, despite the days being long in Summers. So, start your day a little early as the attractions open around 10:00am.
3. Museums are big and covering one of them can take the full day. So don't pack too many attractions in a single day.
4. Be prepared to walk. Yes you can take a cab too but you need to have deep pockets and also you will miss out on the essence of London. The streets, open spaces and the architecture makes London what it is. You need to walk amidst it.
So, at around 10:30am we took the tube from Forest Hill to South Kensington and took us about 1 hour to reach Natural History Museum. We were hoping to cover the Science Museum and Victoria and Albert Museum on the same day. Little did we know that the Natural History Museum would take the whole day.
