Here ya go :) The on/off buses are a great way to get around and see things like "Big Ben, #10 Downing St (at least where it is) The Palace etc. Also you will need tickets to get into most places "Madam Tussauds" (spelt wrong I'm sure) The London Eye (amazing to see the whole of London) The London Dungeon is a fun and realistic look back at London's in-famous criminals. And of course The Tower of London is a must. The hotel will sell you tickets at a discounted price (cheaper than buying them at the place you want to see) Plus if you buy a family package it is cheaper still. I would buy snacks/food at a market/store as the restuarnts are very expensice in London, fish 'n' chips/drinks for a family of 4 will run you about 35 pounds ($60+) Anything else let me know.
