I live near London so don't have to stay there, I just go home ! However if you are going on day trips, use your Tesco Rewards Points for Days Out. I have mentioned on AB before, I got tickets for Mme Tussauds and the Tower of London, both really recommended, and we got in for free with our Tesco vouchers which will save you a lot of money. Also if you want to go around London on a Bus tour, instead of paying for an open top bus, get the Number 6 or 15, it will take you all through Central London, from Marble Arch around Piccadilly to the City. You can get on and off as much as you like. Get a bus map of London and use a travelcard for the day, you can use this on the underground and the buses, and find the best routes to see what you want. Good luck ! By the way, there are probably web pages like 'London on the Cheap" to get money off days out. Enjoy and fingers crossed for the weather ! And watch your handbag .. You can also print off some restaurant vouchers where you can get two meals for the price of one. Try somewhere like Martins Money Tips, he has a weekly email with money-off restaurant vouchers all over London.
